I am seeing some players in my Diablo 3 Friends list showing-up as non-season when in fact they are playing a seasonal toon.
Many players in my friends list will have the word ‘unknown’ by their name and it will not show which character they are playing while hovering mouse-pointer over their name.
Some players are listed as having a level-0 ‘unknown’ character in a t16 game (which is impossible.)
there are also many issues (too many to list) going on while trying to join and start games with other players.
