Hi Rudy,
I don’t have reproduction steps, so I’m unsure how to reproduce it in a clean project. Other people in the Unreal Slackers group seem to have run into the same issue. Hopefully someone will have a better idea of the root cause, but I suspect it would not be easy to identify due to the nature of the issue; because of where the game is getting stuck, it’s pretty hard for me to debug any further with the time / tools at my disposal, but the actual infinite loop itself that is causing the editor to freeze is pretty obvious if you look at the section of code I’ve pointed out. There is already a check within the recursive function there for infinite recursion that allows it to break out and continue, just not within the do_while loop within said function.
