Hey, had two incidents last night at HC on a nightmare dungeon (no dangerous affix) where groups of mobs suddenly spawned on characters idling at entrance late into the dungeon..

What can be done to prevent this?

Which dungeon was it?

I guess not a lot other than dont afk when playing hc

Two different ones, just a random mob spawn with 5 normal mobs right at the Center of the group when carry was near the end of the dungeon. Happened while leveling

It either happens when a mob aggros through a wall (when the map is close to entrance) they will run back to the start

I found out it happens in maps where objective 1 is:
Free x prisoners
Return x stones to pedestools

Thanks for sharing, it might be a way to avoid this by moving in the idle characters 2 or 3 screens into the dungeon From the entrance? I had the feeling the mob pack spawned on the players, but if it spawns at the entrance that changes it a bi

Just avoid those dungs in hc
