That happens when one replaces the "-" in a var in the code, which lateron is not used... Fixed it for V0.9 final...I made that post well over a month ago, lol. Although, while we're on the subject, it would be better if those combinations were to either be kept in the quest book after you use them, in case you want to revisit the scene or you could skip the minigame after you pass it once. Also, please check the belt type input again, cause in v.07 the game still fails to recognise [xliv-xcix].
The substitution code was so simple, that I didn't even test it.
Turns out there is nothing simple
