So basically you just crash with no crash report, when you log back into the game on the same character, you find yourself at a spot that you were in 10-15minutes before you crashed, not at the spot you were during your crash.

What happened to me was that I did a volcanic went, picked up a skyshard and then went off to Gonfalon bay bank after that I went to continue a quest during which I crashed. When I logged back in after the crash, I was back at the volcanic vent and I had lost the achievement from clearing my first volcanic vent, I had lost that skyshard and I had lost the little quest progression I had done.

The thing is that we KNEW about this issue since WEEK 1 pts and it was not fixed for live
