Just got this game, which I did actually pay a fair amount of money for, and can't play because of a bug that makes it impossible to switch items either with the number keys nor a mouse wheel. I have the mac version of the game, and its completely understandable that the game has glitches. Not going to lie though, it's kind of a frustrating glitch. I'm hoping it will go away if I delete my current save and create a new one. Fingers crossed!
