Summary

I have been designing a Game mode for the past few days and it’s happened twice now during a test where the map starts to delete randomly. You’d expect Cntrl-Z to fix what was deleted though it refuses to undo anything deleted by the program and will only undo what I did last. (Before the map was deleted by UEF).

What makes this even more difficult is now after I have double saved the map, it has been getting errors that can’t be fixed. So everything I have done has now been for nothing.
