This party system is buggy....
Issues I'm having is 1) If I join server thru a party system or a specific player from Origin, if that squad is full, I can't join other squad or make a new squad. Only fix to this is that the person who I joined leaves squad and I can join to his squad.
2) When server is full, sometimes I get an error message: and after that joining to that server is nearly impossible, have to leave party and try to join to a friend separately. These problems are making me to miss more own servers with VIP slots.
