they get taken to specific places when arrested, kiri gets spanked on the plaza, emi is chained up to the right of the inn before the next screen
but if you just rest at the inn they get freed sometimes. other times theyre not downstairs you got the rng for them showing up elsewhere.
the first day emi isnt downstairs she's in the strip club watching the blonde repair girl. the day after she's dancing herself.
the princess of fire skill activates because her hp has increased since the last battle.
the slimegirl fight used to have an issue where it disabled the whole portrait battle system by accidentally enabling the side view battle system. no idea if that's relevant to the new issue.
as for the chests... i never thought of anything to put in them.
