--- @interface CustomOptions table
--- * Structure of the main CustomOptions table.
--- * Note: Aliases take priority over parent option name.
--- @within SynSaveInstance
--- @field __DEBUG_MODE boolean -- Recommended to enable if you wish to help us improve our products and find bugs / issues with it! ___Default:___ false
--- @field ReadMe boolean --___Default:___ true
--- @field SafeMode boolean -- Kicks you before Saving, which prevents you from being detected in any game. ___Default:___ false
--- @field ShutdownWhenDone boolean -- Shuts the game down after saveinstance is finished. ___Default:___ false
--- @field AntiIdle boolean -- Prevents the 20-minute-Idle Kick. ___Default:___ true
--- Anonymous {boolean|table{UserId = string, Name = string}} -- * **RISKY:** Cleans the file of any info related to your account like: Name, UserId. This is useful for some games that might store that info in GUIs or other Instances. Might potentially mess up parts of strings that contain characters that match your Name or parts of numbers that match your UserId. Can also be a table with UserId & Name keys. ___Default:___ false
--- @field ShowStatus boolean -- ___Default:___ true
--- @field Callback boolean -- If set, the serialized data will be sent to the callback function instead of to file. ___Default:___ nil
--- @field mode string -- Change this to invalid mode like "invalid" if you only want ExtraInstances. "optimized" mode is **NOT** supported with *@Object* option. ___Default:___ `"optimized"`
--- @field noscripts boolean -- ___Aliases:___ `Decompile`. ___Default:___ false
--- @field scriptcache boolean -- ___Default:___ true
--- @field decomptype string -- * "custom" - for built-in custom decompiler. ___Default:___ Your executor's decompiler, if available. Otherwise uses "custom" if not.
--- @field timeout number -- If the decompilation run time exceeds this value it gets cancelled. Set to -1 to disable timeout (unreliable). ***Aliases***: `DecompileTimeout`. ___Default:___ 10
--- @field DecompileJobless boolean -- Includes already decompiled code in the output. No new scripts are decompiled. ___Default:___ false
--- @field SaveBytecode boolean -- Includes bytecode in the output. Useful if you wish to be able to decompile it yourself later. ___Default:___ false
--- .DecompileIgnore {Instance | Instance.ClassName | [Instance.ClassName] = {Instance.Name}} -- * Ignores match & it's descendants by default. To Ignore only the instance itself set the value to `= false`. Examples: "Chat", - Matches any instance with "Chat" ClassName, Players = {"MyPlayerName"} - Matches "Players" Class AND "MyPlayerName" Name ONLY, `workspace` - matches Instance by reference, `[workspace] = false` - matches Instance by reference and only ignores the instance itself and not it's descendants. ___Default:___ {TextChatService}
--- .IgnoreList {Instance | Instance.ClassName | [Instance.ClassName] = {Instance.Name}} -- Structure is similar to **@DecompileIgnore** except `= false` meaning if you ignore one instance it will automatically ignore it's descendants. ___Default:___ {CoreGui, CorePackages}
--- .ExtraInstances {Instance} -- If used with any invalid mode (like "invalidmode") it will only save these instances. ___Default:___ {}
--- @field IgnoreProperties table -- Ignores properties by Name. ___Default:___ {}
--- @field SaveCacheInterval number -- The less the value the more often it saves, but that would mean less performance due to constantly saving. ___Default:___ 0x1600 * 10
--- @field FilePath string -- Must only contain the name of the file, no file extension. ___Default:___ false
--- @field Object Instance -- * If provided, saves as .rbxmx (Model file) instead. If Object is game, it will be saved as a .rbxl file. **MUST BE AN INSTANCE REFERENCE, FOR EXAMPLE - *game.Workspace***. `"optimized"` mode is **NOT** supported with this option. If IsModel is set to false then Object specified here will be saved as a place file. Only saves the instance itself, not the descendants. If you wish to save descendants too then use @ExtraInstances={Object}. ___Default:___ false
--- @field IsModel boolean -- If Object is specified then sets to true automatically, unless you set it to false. ___Default:___ false
--- @field NilInstances boolean -- Save instances that aren't Parented (Parented to nil). ___Default:___ false
--- .NilInstancesFixes {[Instance.ClassName] = function} -- * This can cause some Classes to be fixed even though they might not need the fix (better be safe than sorry though). For example, Bones inherit from Attachment if we dont define them in the NilInstancesFixes then this will catch them anyways. **TO AVOID THIS BEHAVIOR USE THIS EXAMPLE:** {ClassName_That_Doesnt_Need_Fix = false}. ___Default:___ {Animator = function, AdPortal = function, BaseWrap = function, Attachment = function}
--- @field IgnoreDefaultProperties boolean -- Ignores default properties during saving.  ___Default:___ true
--- @field IgnoreNotArchivable boolean -- Ignores the Archivable property and saves Non-Archivable instances. ___Default:___ true
--- @field IgnorePropertiesOfNotScriptsOnScriptsMode boolean -- Ignores property of every instance that is not a script in "scripts" mode. ___Default:___ false
--- @field IgnoreSpecialProperties boolean -- Prevents calls to `gethiddenproperty` and uses fallback methods instead. This also helps with crashes. If your file is corrupted after saving, you can try turning this on. ___Default:___ false
--- @field IsolateLocalPlayer boolean -- Saves Children of LocalPlayer as separate folder and prevents any instance of ClassName Player with .Name identical to LocalPlayer.Name from saving. ___Default:___ false
--- @field IsolateStarterPlayer boolean -- If enabled, StarterPlayer will be cleared and the saved starter player will be placed into folders. ___Default:___ false
--- @field IsolateLocalPlayerCharacter boolean -- Saves Children of LocalPlayer.Character as separate folder and prevents any instance of ClassName Player with .Name identical to LocalPlayer.Name from saving. ___Default:___ false
--- @field RemovePlayerCharacters boolean -- Ignore player characters while saving. (Enables SaveNonCreatable automatically). ___Default:___ true
--- @field SaveNonCreatable boolean -- * Includes non-serializable instances as Folder objects (Name is misleading as this is mostly a fix for certain NilInstances and isn't always related to NotCreatable). ___Default:___ false
--- .NotCreatableFixes table<Instance.ClassName> -- * {"Player"} is the same as {Player = "Folder"}; Format like {SpawnLocation = "Part"} is only to be used when SpawnLocation inherits from "Part" AND "Part" is Creatable. ___Default:___ { "Player", "PlayerScripts", "PlayerGui" }
--- @field IsolatePlayers boolean -- * This option does save players, it's just they won't show up in Studio and can only be viewed through the place file code (in text editor). More info at https://github.com/luau/UniversalSynSaveInstance/issues/2. ___Default:___ false
--- @field AlternativeWritefile boolean -- * Splits file content string into segments and writes them using appendfile. This might help with crashes when it starts writing to file. Though there is a risk of appendfile working incorrectly on some executors. ___Default:___ true
--- @field IgnoreDefaultPlayerScripts boolean -- * **RISKY: Ignores Default PlayerScripts like PlayerModule & RbxCharacterSounds. Prevents crashes on certain Executors. ___Default:___ true
--- @field IgnoreSharedStrings boolean -- * **RISKY: FIXES CRASHES (TEMPORARY, TESTED ON ROEXEC ONLY). FEEL FREE TO DISABLE THIS TO SEE IF IT WORKS FOR YOU**. ___Default:___ true
--- @field SharedStringOverwrite boolean -- * **RISKY:** if the process is not finished aka crashed then none of the affected values will be available. SharedStrings can also be used for ValueTypes that aren't `SharedString`, this behavior is not documented anywhere but makes sense (Could create issues though, due to _potential_ ValueType mix-up, only works on certain types which are all base64 encoded so far). Reason: Allows for potential smaller file size (can also be bigger in some cases). ___Default:___ false
--- @field TreatUnionsAsParts boolean -- * **RISKY:** Converts all UnionOperations to Parts. Useful if your Executor isn't able to save (read) Unions, because otherwise they will be invisible. ___Default:___ false (except Solara)

		Thank you for using UniversalSynSaveInstance (Join to Copy Games) https://discord.gg/wx4ThpAsmw.

		If you didn't save in Binary (rbxl) - it's recommended to save the game right away to take advantage of the binary format & to preserve values of certain properties if you used IgnoreDefaultProperties setting (as they might change in the future).
		You can do that by going to FILE -> Save to File As -> Make sure File Name ends with .rbxl -> Save

		ServerStorage, ServerScriptService and Server Scripts are IMPOSSIBLE to save because of FilteringEnabled.

		If your player cannot spawn into the game, please move the scripts in StarterPlayer somewhere else. Then run `game:GetService("Players").CharacterAutoLoads = true`.
		And use "Play Here" to start game instead of "Play" to spawn your Character where your Camera currently is.

		If the chat system does not work, please use the explorer and delete everything inside the TextChatService/Chat service(s).
		Or run `game:GetService("Chat"):ClearAllChildren() game:GetService("TextChatService"):ClearAllChildren()`

		If Union and MeshPart collisions don't work, run the script below in the Studio Command Bar:


		local C = game:GetService("CoreGui")
		local D = Enum.CollisionFidelity.Default

		for _, v in game:GetDescendants() do
			if v:IsA("TriangleMeshPart") and not v:IsDescendantOf(C) then
				v.CollisionFidelity = D
			end
		end
		print("Done")

		If you can't move the Camera, run this script in the Studio Command Bar:

		workspace.CurrentCamera.CameraType = Enum.CameraType.Fixed

		Or Destroy the Camera.
