There mostly spawns a pat behind the barrier at the end of this picture. (the room after the 1st grim)
So i had it 2 times yet, that the patrol spawns , when you pass it. ( hear the audio) Just a barrier separates the players and the patrol in this moment.
Everyone just run fast upstairs and all seems fine,but suddenly the patrol get pulled from ???. They probably mention, that we´re upstairs. Noone were near them and we all were fighting a horde / SV upstairs. They got instant aggro, after they jump over the barrier. So please fix that FS.
