Guild Wars 2

If I drop turrets, they seem to only work until all the initially aggroed mobs are dead. After that they are ignoring anything else that attacks me or that I am engaging.

Am I doing something wrong, or is this a bug?

did you attack anything after for them t pick new target?

Yes. I had a mob that I pulled with the shotgun right next to the turrets. They just sat there doing nothing. I even overcharged them to see if that made them react.

I’d suggest you repost that here.
I can’t confirm it, but if their AI is broken, that one should get taken on the list.

I closed and reopened my game and it seems to be working. Will report if it happens again.

Happens to me occasionally in PvP. The turrets attack fine the first person that I am targeting when activating the turrets but then if the person dies and a new enemy comes the turrets would just sit and not attack the new enemy.
