So after I posted this I played a full day with no crashes, luckily, but the problem that makes the game definitely crash is still there. Even as today.

Hey boys, I have a Space Exploration + Krastorio + some other small mods game we have been playing together for more then 1000h. I haven't played in a week and started the game again this night but the game keeps on crashing for me. My friend hosts the game on his master pc and I play on a Mac Mini....
