So I've had a weird bug that I've tried to pin down for a few months now, and I've come to the conclusion that it happens completely randomly. (As in, it happens online, offline, when the game is paused, when the game is not the active window, etc.)
On the Mac version, my game randomly freezes the entire OS. The game freezes on whatever frame, and I still hear the background music, but no sound effects/voice lines. I can still move my mouse, but I can't click on anything, I can't even hover over apps to see the name of it, I can't cmd+q to force quit, etc. When it happens online, the other person just sees it as a crash, but on my end I can only hard reset my laptop. If I try to wait out the freeze, I occasionally hear about a half second of voice lines/sound effects, usually whatever would have happened immediately after the image freezes, and then it continues to only play the music. The video does not update when this happens.
When I turn my laptop back on, it gives me a crash report, which i've dumped into this pastebin:

I think I made a reddit thread when I first encountered this issue but this is probably a much better place to report this sort of thing.
