Never had any issues of the sort. Normally it's quite fun and chatty.

Last time I done it a few were watching the cutscenes for the first time (having run it often enough as speedruns) and there were lots of comments of "oh so that's what happened there...I see" "Ahhhh well that makes sense. I always wondered how we end up here" We were even joking about how jarring it can be when someone up ahead in Castrum activates the cutscene for the final boss and you see your character walking through the doors. Only to jump back to the game and your miles away from the doors you just watched yourself walk through. The things you pick up on and have a laugh about. Anyway, point is, no toxic nature. I'd think anyone of that is either trolling or left because it's not like you don't know wat youre getting into.
