One player cannot see teammate icons on the map in multiplayer mode, while other players can see them normally.
Not a consistent occurrence, but sometimes in multiplayer other players do not populate on the map. It’s never been everyone on the realm, and it’s never one realm–so no commonalities have persisted between instances of the issue. Leaving the realm and rejoining hasn’t been a fix, but restarting has.
You mean strictly their icons right? Or are they in their entirety invisible?
