UE4 Crashing

I am creating a map using the UT editor and I’ve recently started getting a strange bug, whenever I push play the engine crashes and closes, it says no dump was generated.

This is of course a massive problem, as I need to test the map, I am getting no indication of why it close or how it could be fixed.

Does anybody know where I might find a log or file that could contain information on why it crashed?

Ask that in the official UT forum:

These people know the UT stuff very well :3 and they will help you very fast.

Thanks, I was not sure where to post this.

I’ll head over there now.
