chilly vortex
Version 1.0.1g-FULL on Steam.
I used immolate on a booster pack selection screen after (accidentally) having shrunk my max hand size to 5. The skip button became grayed out, soft-locking the game. I was able to exit to menu and reopen the run, but using immolate again resulted in the same soft-lock. I was able to progress without using immolate there, and eventually got a tarot pack with emperor. The same bug occurred there with the skip button graying out, but I could use emperor to progress. I was too scared to try it in a blind for fear of bricking my run, so I don't know if something bad happens there too.
(Didn't see this reported elsewhere, sorry if I missed it.)
