The Camera issue is just a error. You won't find 1 person with this game that DOES NOT have that error.
For the inventory issue check out your settings. Somewhere in there is the options.
To save, complete a part, you cant just randomly save. That is a pretty crappy part. Enjoy the game!
I would like to beta test YOUR models
I love graves. You should love him too.
