About an hour ago we we’re doing an All mesmer party Arah path 3. We managed to get to Lupicus and there we noticed something weird. None of our phantasms were attacking Locusts or Grubs. Everything was fine when we cast on Lupicus, but when cast on Grubs, nothing. They just stood there. So we were stuck where we usually have no problems, since phantasms were a huge part of our dps.
Provided a video. It might not be seen the best, but in the 1st part, Berserker spawns on Grub, but just stands there. In the second part Warden is cast on Grub and it also just stands there. Failed to record where they do not attack locusts, but it was the same with them.
