I just tried to delete a variable in Event slot of Active, but accidentally click ok on "Lost all event about this active" because I thought they mean the variable, so
accidentally delete my Active, now I Click Ctrl+Z to undo delete, I don't think anything at first and continue on working, but then I realize that all the event
about this Active is not recover as the Active did...
Now, it like my whole project is deleted because that is my main Active, the player.....
I'm very angry about this, why don't you make undo work on event too(That connected to this event).
And how to fix this?
