yeah, unfortunate. prob gonna wait an update and see if it gets fixed/finished. thinking about just starting a new game but since its not renpy it sounds pretty miserable to skip throughsadly seems like no fix coming yet for the sister's party, so the work around for now appears to be, once the sister tells her about the party, you got to say no other wise you will be stuck in the party loop, also dont call sister after you say no, because at some point when your trying to progress with the sister after you say no to the party idea it will freeze the game and you will have to relaunch the game, what i found anyhow.
