I hope someone from Epic can help us out here.
We’re trying to decipher how IOnlinePartySystem is meant to be used with a persistent party. We know it involves UParty, UPartyGameState, and UPartyMember state but all updating of that passes through IOnlinePartySystem.
The entire thing is very open to interpretation, which isn’t a bad thing, but it’d be nice if there was some direction or template on how to use the interface.
