Hi there, you may want to upload the "Debug.err" next time you run into a crash. It will help finding the correct debugging information for the developers to help fix the bug that crashes the game, I am happy to see you hit the right forum sub-section (I had some trouble with that
)

That link is to the official "How to report an Issue" thread, which goes through where to find the "Debug.Err" file, and a tip of how to upload it.
Thank you in advance, and thank you for taking the time 
Sincerely
