(Scenario)
Player A builds a house on Server 1
Player A leaves Sever 1 and joins Server 2
Player B joins Server 1 and looks at Player A's house which says "Owned by Player A"
Player A creates a group, and calls it "PlayFabRocks"
Player B sees the house details show "Owned by PlayFabRocks" instead.
The transition occurred while player B was not on Server 1, how does server 1 get a Notify of group changes (which I dont imagine scaling for thousands of servers with any sort of TPS)
Is PlayFab an effective solution for this scenario?
