Crowbell boss in t3 map went invuln, kept attacking/no phase 2

Maps in the area had boss tablet unique that gave them azmeria spirit, the spirit was bear, and after a certain period of time the boss stopped being targetable, kept attack (and was doing damage), and wouldnt change phases.

idk if its normal or not but the respawn at checkpoint option in the esc menu wasnt present. i tried to logout and move my character to base/town with the button at character login, and re-enter to see if it changed anything. Boss was in arena but upon entry bug was still present. Notably, the second room of the boss arena was open during the fight, so maybe it was a phase change issue



the attached screenshot shows a list of the map modifiers, and the amount of HP boss had; im a blackflame covenant blood mage with phys/fire spells/reap

Got the same bug in a T15 against The Black Crow.

Same problem t15 map on my ssf cold bloodmage, even did a dmg stop because i heard people having this bug.

Same bug reset and tried 3x gave up and wrote the map off
