Only minor things as far as I can tell. I'm having no problems playing 1.3.1 in anyway. So don't let it stop you from playing.Sounds like there are plenty of issues with the new release? Can we expect a 18.104.22.168 release in the near future? I was thinking of holding off starting playing the new version, if hotfix version is on it's way. Or is there such a version coming? I can play some other games in the meantime.
