Perhaps my understanding is somewhat lacking here, but there I was on a Heist (Secluded Sewers), about a minute and a half remaining to get back to the extraction point (tight but doable), when some Werewolf comes crashing in, slaughtering everything in the room, which alerted the guards to me and blew my otherwise perfect heist. Whose bright idea was it to send another player into my Heist instance? Or are these intended to be shared?
I'm fresh out of outrage, but I could muster up some amused annoyance if required.
