Three times in 4 days my friend and I have had 3 different shared saves crash resulting in us losing hours of progress, our entire inventory, and on one occasion an entire save to corruption. We can't progress the hedge lab because the activation lever doesn't exist. The very first analyzer quest never completed and will not go away. There is insane degrees of rubberbanding for non-hosts. Dropped loot routinely dissappears through the floor. The majority of our player deaths are a result of becoming trapped inside or partially inside geometry and for 6 in game days on our most recent save there has been a wolf spider that traps it self inside the log our base was built on (regardless of how many times I tell the game to reset bug locations) causing us to be perpetually in combat and unable to build in that location.

I no longer have patience for games that expect players to put in dozens of hours that can random erase that time without warning or recourse. 

There are no backups of shared saves, no way to roll saves back, no console to fix problems. I have spent more time fighting to get this game  to actually work as advertised than I have genuinely playing it and having fun. I no longer have the will or patience to continue doing that.

I love the game, but as far as I'm concerned it's unplayable.

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.
