I just had a crash on my singleplayer world. I had opened it to lan, because i had to tweak something and when i quit it crashed.
I tested it 4 more times and it didnt crash. Maybe I just quit at the wrong moment or something.

Thanks for this report - that would probably be hard to catch otherwise.

No problem :) im always happy to report anything wrong and funky to improve it.
