[Jedi515]

P much self-explanatory, but just in case, that's what the log says

Went through one endless cycle with a few crashes, but once i got to the city second time it just went poof and refused to ever load. Gimme back my zylophone'd clockwork chicken...

Possible issue - rune of simplicity arguing with megaupgrades? I had a mega'd defense along with simplicity +2'd defenses.
i also saw at the last fight bottled soul switch its target from what it is (apparition) to that draw-2-cards jar card.

Should I copypaste it to construct thread?
