Templar Shields Causing Game-breaking Bug in Diablo III
I know you are probably knee-deep in Diablo III by now, but hold off the game for a second and heed this warning that is setting the Blizzard forums alight: Don’t give your Templar follower another shield or it may screw up your game.
Players have reported being disconnected from the Diablo III servers after interacting with the Templar, a follower character in the game, and handing him a shield. Players are then faced with an Error 3006 and are unable to get back into their game, or even their Battle.net account.
Blizzard’s Diablo III Forums’ Known Issues List cites the issue as:
When playing a Demon Hunter, giving a shield to your Templar before you kill Jondar and hire him can disconnect you from Battle.net.
Blizzard is working on this issue and will respond with a fix for the bug. So keep your gear to yourself for a bit, m’kay?
