Ok, so i figured out the craft-crash only happens when I try to do it with my main character, I can craft with my alts. This is not a big deal, but it's annoying to know I can't do it. When I press the hoi-poi mix button at the machine, the game crashes. I have a portable mix-machine (which I see isn't available in the game anymore :P) and it happens there too. Maybe the problem was with all the recipes and stuff I had with my lv70 char with craft lv9 - they deleted and reseted everything. So this is why I CAN craft with my alts.
But if that's the problem, why could many of my friends craft, even when they had a ****-ton of recipes before the update? And if that's an update(software) issue, why does it only happens with my swordsman?
