Yeah, if you enjoy leveling up, putting points in skilltrees and buying weapons in safezones I'm happy for you, casuals needs something to play aswell. I got the same graphicbug but I'm patiently waiting for the DayZ-team to fix it. The mod is in a very earlystage, you can't expect things to work. Rocket could've decided to only let a small amount of people play the Alpha. Instead he's letting everyone play it and report bugs.
