Hey so my friend keeps crashing when playing on my world. We have like over 100 hours on our save and only recently started breaking when we were placing a bunch of containers and conveyor belts. Now he crashes after 20-40 mins in the save. Oh also, we are running mods: Curve builder, Faster manual crafting and No z fighting. We did have structural solutions and infinite zoop but he still crashes after removing them. Also I booted it up in vanilla and he joined and still crashed. He has reinstalled his whole game and nothing has changed.
Here are his logs and the game file:
