Ive had a similar issue with Inventories being lost after game crashes. Upgraded armor and weapons just vanish after reloads. Backpacks being retrieved to have nothing in them. The rubber banding for non-hosts is horrible. This is one of the few games my wife, son and I play together. Having to start over multiple times only to progress to where we were and getting the "Crash erase" is a bummer. We had taken a break to wait for the official release and were very excited to see all the new content. So much progress just gone.
