You should def override the party condition so the mod works again

Damn, you're right.

I'm fairly certain that parties are now only able to occur if there's a Party Girl in the world now, effectively making this mod useless unless you reverted the conditions for a party to not need the Party Girl (like it was before 1.4)

oh I like this idea and I wish to support you in your future endeavors :)

Should be a Vanilla feature.

Honestly both a unique and fun way to incorporate a spawn condition for her!
