Couple questions...

Was playing when a friend just got done patching/installing... I completed the first few story missions the other day, he joins the game, we group up, and proceed to do his 1st few missions... When we went to the area near the crash site to do the medical mission his screen showed me as a box and same with mine, the area was empty on my screen but on his he was doing the mission.

Any idea why my screen didn't show what was going on in his screen? Was it just because I've already done the quests?

Other question about 2 hours into our session right before we did the episode mission where you go into the mine to get the gem it disbanded us from a group, I left and rejoined and still couldn't group up, we could teleport on top of eachother but he was blue not green and no health/shields on my screen for him. We had to go into the mines separately where he got slaughtered w/o me...

Just curious...
