the game crashes when you press Ctrl + Z too many times in the MediaTracker. I guess it happens, because the game only stores around 20 undos. Issue is if there is no more undo stored, the game dies. To fix that problem, instead of doing the undo function, it should check if the undo is not empty and then do it. The bug is quite annoying, as you can't really tell when to stop.
Reproduction steps:
- Open the MediaTracker in any way.
- Edit clips loads of times.
- Press Ctrl + Z repeatedly.
- Watch the game die.
