Guild Wars 2

I have noticed several times that certain turrets in the Save Our Supplies guild challenge do little to no damage. The normal shot will do about 98 damage while the napalm will hit 3 rounds of 0. This has made it rather difficult to take out the stalkers on the southern side. I have tested this on the southwestern turret. We did this challenge previously (a month or so before) and the turrets and napalm were hitting for well over 9000 damage. If possible, can this please be fixed and soon, as the Save Our Supplies challenge has been the guild challenge we receive well over 70% of the time.

I believe is a text bug. I was controlling turret just awhile ago and doing 80-90 damage per hit but when I look at the HP bar of the mob, the hp bar drop around 1/3 to 1/2.
