Unable to complete GG subdungeon

[Elswyyr]

Whenever I try to do the subdungeon that unlocks GG, I immediatly get an error message upon touching the final altar. I am transported back to town, and the run counts as a lost one.

Yup, it's been a known bug - sorry about that. Good news is it's already fixed and will go away after today's update.
