I can definitely confirm this for you. I didn’t know anything about this bug and did the world complete. Next thing I know in WvW everyone seemed to magically know which were clones and which was me.
My Mes is basically broken for WvW now, it’s either reroll another char for WvW or stick with Pve (that will suck), problem is after so much time and energy the thought of rerolling isn’t very appealing either.
