Iron Citadel can't be completed (even with rares monsters + boss, all killed)

I'm aware there's a bug that if the map has no rare, it cannot be completed even if there's 0 monster remaining.

But I just did an Iron citadel, there was multiple rares in the map (as well as the boss) I killed all of them including the boss, and the map didn't complete. Not sure if rares can spawn in the poem phase of the boss but I didn't reach that phase as I killed the boss too fast.

Here's a screenshot at the end with no rares on the map and 8 monster remaining : https://imgur.com/a/7En3x79

here's another one, 1 monster remaining, same situation. https://i.imgur.com/FvwWrjq.jpeg

I've found 2 so far, and I haven't been able of complete any of them

Happened to me too, it looks like the boss is still considered alive and i can see his icon and hear him breathing after I killed him.

Man, this is brutal. Sorry this happened to you. I'm just going to stop chasing after these myself. It just feels wayyy to bad to invest so much time into finding one, slogging all those boring basic maps for 8m xp a hour, trying to dance around towers and so on just to have 20-40 hours of raw gameplay thrown away due to a bug.

Happened to me as well...

Same issue two iron citadel lost they should put this as a major bug and fix it...

same thing just happened to me too

same thing happened to me

same here.. killed everything, boss icon still in arena, 1 monster remaining, my character glitches when I run over the boss icon in the arena..

Still the same.

Just completed iron citadel, it shows 1 monster remaining; map not complete.

Killed the boss and every single monster on the map.
I ran around the empty map for like 20 minutes to check every corner and every room, there is nothing left, certainly no rare, which would be required to finish the map.

As soon as I start a new map it will say "map failed" on the iron citadel, of course.

Had that already 2 or 3 times, in each iron citadel I found.

Not sure if "map failed" is relevant for anything, besides not being able to travel from there to the next maps but certainly feels bad.
