This started happening about a week ago on PC/EU. When we queue as a group for a dungeon now and then (maybe 5% of the time) we get a situation where
- One group of players is ported into the dungeon and the others are shown offline
- The remaining members are left where they were before and see the dungeon group as "offline"
The people outside cannot port to those in the dungeon, but weirdly enough if they walk in through the dungeon door it fixes itself.
Other than having a very wide range of latency/bandwidths so time to port in I can't think of anything that's different or odd about our group to cause it.
Too many toons not enough time
