Hi all, I've been playing a co-op game with a friend of mine for a few days now with no problems, however yesterday the game started to crash (shut itself unexpectedly with no warning) on my end (I'm the host) after we play for 5 minutes or so. It's also noticeably laggier for my friend. I can play in solo mode with no crashing at all. Is there a fix for this issue? Thank you!
