Bossfight refuses to start in maps!

Step 1, do all the maps with wisp to unlock mansion
Step 2, get a tier 6 map
Step 3, open mansion with some juice on it
Step 4, get scammed out of a lineage support, when the boss refuses to fight start.

Some extra info, i cleared every monster in the map aside from the bosses, and double checked every room a second time. The map still thinks there are 50 monster remaining for some reason, and i doubt the bosses each count for 25.

Boss fight refuses to start entirely, going to char creator doesnt work, going to main menu doesnt work, quitting out and reloging in doesnt work. Its just bugged somehow.

Ill try and check if its still up tomorrow, if the after the 15 min timer resets, but i expect it to jsut be gone, which tbh sucks ass. Mostly due to the large buildup required to get to the mansion.
