How seriously annoying.
After 4 attempts with a pug we finally got past Fizz in the lazer room, grabbed loot from chest and proceeded on, in the next fight we were just taking down the final mob when … zap.. the whole group gets ported out of the instance and back to LA… cheers ANET!
Then I find that cant interact with any NPC either, cant activate bank or use the forge… totally borked!
