Eh it kinda happens everytime they do these new versions, need to wait it out some more as usual.Kind of defeats the purpose of re-releasing the game with a new appid to reset its user reviews if you're just going to shove it out the door in the same shitshow state as the original release.
lol. wtf.Update
Current list of known bugs is huge (think release of the original huge). Crashes on saves and the likes. I get massive FPS drops when looting or going from menus back into the game. Go from 60, crush a barrel and loot, exit the loot menu, drop to 35-40fps, then a second or two later, it goes back to 60. Very noticeable.
Might want to let it cook for a patch or two before starting.
