I was trying to make a toggle crouch, and it wasn’t working. I put a checkNoReentry() to my ToggleCrouch function was getting called twice, and it was. My editor crashed because of the assert, but after restarting everything worked.
I just put this here instead of anyone else was getting a similar problem. There’s also a problem when switching the default GameMode. It’s strange that if you restart the editor problems can just go away.
