Guild Wars 2

I just did a dialy T4 run and on level 97 the boss bugged out and started jumping to the side of the platform. We could still kill it, but it made the fight a lot harder (with a couple of wipes) then usual, but also more interesting.

There have been a couple of reports about it; the devs are aware of it & working on identifying the cause.

Just had this happen to us too – it was all the way on the edge, ported back to the center at 25% for a second or two, then ported back to the edge again. really inconvenient.
