at the start of the game (PC, Steam, Multiplayer) I got stuck in the first pneumatic tube in the intro. I entered, went to a black screen, and game froze. I had to force close the game. After that, My character was immune to insect damage. The way I ended up fixing it was i died to fall damage, with my wife too far away to save me. It was my first full death/respawn. after that, I was no longer immune to damage.
