Stuck in the black cathedral

I was doing the boss,at the end he opened a rift and i was in it so i got stuck. after killing the boss I used the "respawn at checkpoint" to come back and get the loot. not only the loot dissapeared but now im stuck there and there is nothing i cvan do to get out. tried relogging, /hideout , opening a portal, to go to the guild HO , it wont let me as it says i cannot leave during a boss encounter. tried to respawn at checkpoint again and still nothing, I even tried to have someone invite me to party so i can tp to them. notning seems to work

fixed, some Gigachad in global told me to click ctrl + play in char selection screen and it will take me to the last town.

ty very very much!!!!

I got stuck at cauldron
I didnt give up my loot tp to checkpoint... I used a portal, got a travel skill (desengage) and used when returned to the map
