who ever does have the bug with the 13 day you can still sell stuff just use the sell table as inventory the customers will buy the stuff then but they can get stuck then.
I've found other bugs too...
1. when i buy a polearm grip and some other grips in the same box the polearm grip is bugging through the ground.
2. If someone comes online by steam or starts playing a game on steam it kicks me on to the desktop (options: fullscreen)
3. I can grap stuff through the walls and drag them through windows
4. I can jump through all windows
The game is still awesome. I have much fun with it and i would like to donate but for me its a bit hard to get a paypal but there will be coming soon a donate :).
