Bug Report: Can't TP out from Black Cathedral boss fight

Hello! I would like to apologize in advance for any grammatical errors or inconsistencies in the names of mechanics, locations and functions of the game while reading this report. I use Google Translate due to the fact that I speak English poorly.

Situation: I used Kulemak's invitation in the Black Cathedral location. I went through all the stages, defeated the final uber boss and at the moment of his death, my character died the same way, I looked at the items that fell to me, sighed sadly and pressed "revive" thereby losing everything. EVEN THE POSSIBILITY TO LEAVE THE LOCATION.

After reviving, the "call portal" button cannot be pressed, and the window that appears says: "You cannot leave the area during the battle with the boss." I tried to re-enter the game, re-enter through the "character selection" menu, nothing helped and now I decided to wait about 30 minutes with the game closed and tried to re-enter, to check if the location closed itself and the game teleports me to the shelter or location for any act.

Ultimately, the problem was somehow solved, when I re-entered after 30 minutes, I remained in the same location, but I was able to press the button and exit.

p.s. At some point, I began to think that now I myself am the boss of the Black Cathedral location.
