Guild Wars 2

Now and then I come across enemy dolyaks bringing supply to a camp which are invincible.

It is as if they are not there, I keep hitting them but no damage is done and if I target them it appears as MISS (same as when the target would be out of range)

Occasionally dolyaks will appear to be a good 40-50 feet from where they actually are when they are on the move. I.e. you will target the yak and watch your character fire in a completely different direction.

Not sure if this is related or a separate bug.

They also teleport at times, even with low lag. Probably all related.

I can confirm that this is still a problem. I just was attacking a Dolyak from the SouthEast Camp all the way to the SouthEast Tower. I put CC skills and things that are supposed to block it and stun it, but the Dolyak was unaffected. Every hit showed as a miss.
