Teammates Frozen during dungeons

In 80% of the dungeon quests I encounter this problem. While progressing thorugh a dungeon, all of a sudden it appears as if 1 or all of my teammates have disappeared. I can no longer target them or see them (but in reality they are right next to me) and can see me fine, this only happens on players, not on their summons. If I check the map, they are shown as being in an earlier room. I can return to that room and see them and target them but they rnt moving. No matter how far we progress in dungeon they will always "stay" in that one room. The only fix that ive found is for me to die and return to start of quest, or for them to die and get raised by someone else or return to start and back. It is such an inconvenience not only on myself but for my team as well. PLEASE HELLPPPP!!

I'm having the same probelm and I hate it =/ It makes it so hard to help everyone out. I hope there is a fix soon

i get server lag in the instances also and its just server lag on my screen i can run around but every one else is still,
so im just guessing when i say this but there seems to be a small 5-10 sec sever dc when im in instances.
then everything speeds up and finally im back on track with the team and can keep going :)
but ppl are dead sometimes by the time im back up to speed.
AoE's!!!! brutal in instances for me, in game i can avoid pretty much everything and in the instances i clear the red zone but i still get hit by them...
im think the issues might be connected becasue it is only instances i get these issues.
does any one have a solution to fixing this?
