Copperbell Mines Party Member Issue

Hello,

Last night, during Copperbell Mines, one of my party members was, on my screen, still at the entrance to the zone. Apparently, they were actually with us, but I was unable to target them or heal them, apart from using area of effect healing abilities on conjurer.

I could see their blue line targeting monsters (it came zooming through walls as they were at the start of the zone on my map) and their damage. The other party members could see the player standing near us, it was apparently only me with this issue.

It was not a real drama, apart from wanting to target the player to heal them. Thankfully they were not the tank.

I did not read through the forums to see if it has been previously posted, please forgive me.

Just to make it clear, I could not see their character model with us - to me, the character was standing at the start of the dungeon.
