There were two issues I had to fix:
1, lua kept crashing. I had to manually give lua more mbs, something that should have been done by default
2, and this is an issue on my part most likely, but still, I had to set up virtual memory.
any way please work on fixing the game, i should not have had to fix the first issue on a brand-new game!
i would expect more out of fatshark as I have played vermintide for a long time without any issues, but here we are.
