Myself and guild mates have had the game crash while in battles losing cantina energy.
Clicking on a toon to see if they are modded (ally for example 1) removes that toon as an option. Then clicking a toon in arena to see if they are modded is losing that opponent as an option.
Guild chat is seriously messed up. Half the time it's gone. Huge gaps between messages. All chat is pushed super far to the right cutting it off.
And GW is still a nightmare and has gotten worse with mods.
