Using Arc weaponry will probably make the game crash. Arrowhead has confirmed this and is working on a patch. Release window is early next week.
No Arc thrower, Arc shotgun, or Tesla tower until next patch.
… Reminds me when emoting on Vermintide 2 would crash the game…
Played for 4hrs after the patch, no crashing on our squad of 4. Hopefully they get it resolved quickly
