Party Limit Begone

does anyone know this mod(party limit begone) and can tell me their experience? does it cause any serious problems?

the mod description says: "Some ingame events are hardcoded for 4 party members and will glitch out. This is usually solved by either dismissing the additional members/players or by teleporting back and forth."

"by teleporting back and forth." what is meant by this? so sure it's probably about fast travel. but should i just send the additional characters somewhere else before events happen or how do you understand this?

and have you encountered any other problems?
