Coupla bugs
1- the game quit unexpectedly upon first startup, but was absolutely fine after that. That's probably not even worth worrying about but I thought I'd mention it while I'm here.
2- there seems to be some line of sight issues when it comes to terrain- I had a couple of times where a demon 'spotted an enemy' but that demon was waaay in back and definitely couldn't see anything, though other demons maybe could(no red dots appeared iirc either in these weird cases). Also, a faerie managed to hurl an Ember Burst through a wall, which seems possibly related
3- Shojo negotiation is HELLA bugged- the game froze upon opening the negotiation screen and the negotiations were, well...
Oh, another thing I thought I'd mention as a possible AI bug
Some Barbegazi fighting Turdak decided to use punches instead of Cryopulses. Turdak had been made Chthonic so he resisted everything they did, but it made me wonder- should they have been smart enough to realize auto-hitting and Frost-Armor-triggering Cryopulse was superior, or were they just conserving SP since none of their options were good?
