So I noticed this in the news:
I logged in for a couple of hours to play, still a fair bit of rubberbanding happening on and off but I decided to push through it and go to Munteen.
Seemed to be going well, I started killing things and piling up bodies to loot once I cleared the area. Then a spot of lag hits, I end up dying to a spitter after watching my bullet kill it but never seeing the bullet that hits me due to rubberbanding.
So, return to sanctum, re-enter Munteen, and.... all my bodies have disappeared. I'd piled up 2 roadrunners, 7 or so cuttletrunks, 2 hoppers and 2 spitters. All carcasses were just gone.
And that was the end of play for me, very frustrating and no fun to play!
