I remember I could buy magazines when I started my game, but I can’t anymore. I did a little bit of testing and it seems that after you do a save/load cycle, you can no longer purchase them anymore, which is rather annoying as they’re a good way to get a little bit of an extra boost.
Ok I’ve fixed this, but not done a patch for it yet. if you re-download the entire game, you should get version 1.06, which has this bug fix in it.
Cheers!
