experiencing this bug again. identical issues. kill guardian, trash spawns.
kill trash to steps, nothing appears.
we tried this event yesterday too and when we got to the stairs there was a truly huge number of mobs there waiting for us. 4 or 5 big red demon types with 3 to 5 support for each demon.
Our meager T3+ geared toons went down super fast to that much raw combined damage. so, i have at least seen that far into the script.
was going back today to see if that is part of the event and you have to split them somehow, etc....but nada spawned after guardian / trash was down.
so, hoping for two things....
1) event is bugged, but fix is known already
2) not supposed to have 25 mobs all at once

it is difficult to get my crew together across multiple time zones. if you put a fix in place it could take a week or more before i can personally test again.
sure would like to get past this as it is a big content bottleneck/blocker without relying on seldom seen tokens these days.
will answer questions if needed...
thanks
