Taunt makes me teleport

When I taunt with a templar using enduring cry and im near a passage sometimes i get teleported to the previous room with a very strange glitch is that commom ?

That's lag. Because your client is not in sync with the server, you go to the point where you was on the server before the sync-issue. Related stuff caused by desync: Getting damage from invisible/far-away monsters, not hitting a mob for some time and the mob "teleports" to some other spot, instead of going to the next area, you 'teleport' to an other (previous) point.

There is not many you can do to totally prevent it. Things that help is not running internet connection heavy programs (like torrent programs) or cpu intensive programs (like backup programs) while playing PoE.
