Basically what the title says. The Undo button in Studio forgets what it un-did before, resulting in things getting lost to time. It remembers most things but sometimes it can’t even remember a part being in a specific location before. I have no idea what is causing this, and I don’t know if anyone’s ran into a similar issue.
Expected behavior
I usually expect for Undo to work as intended, restore something I deleted or revert an item. Sometimes it doesn’t do that.
Not all actions in Studio trigger ChangeHistoryService, which is used to store information about changes, using the command bar is one example of this.
If you explicitly destroy an Instance, you cant restore it because Undo would otherwise change the Parent of the instance (which you cant do here, because Parent gets locked).
You also cant Undo while the game is running because its changing literally every frame.
