Mushroom Kingdom - Prime Minister not spawning

[P0nk]

"(...) in the Mush Kingdom the Prime Minister isn't spawning, the princess doesn't offer the interaction to spawn him either."

For what it's worth, I was able to complete the entire Mushroom Kingdom questline by playing through it normally (including spawning the Prime Minister).

tbh the error seems like they aren't in a party and the code isn't handling that case
