Oh!
Well, that's a major relief then. Thx for calculating that for me

Yeah, I would assume 2MB wouldn't hurt much, even though I'm not 100% sure that they take excactly as much space as a "normal" integer. I remember reading about the memory print of flags vs modifiers vs variables somewhere... they have their name to store as well. But anyway, I feel almost confident enough to risk it now ^^
That last part is interesting, but I doubt that it really works that way. For example, if some calculation means that prosperity_value would end up as zero, but later would be increased again - then the variable would first disappear, and the latter operation fail? Doesn't really seem right.
So yeah, thx a lot for answering, but I feel a tiny bit confused now so I'm gonna do a think I rarely do, and bother someone official:
@Meneth or
@blackninja9939, can someone confirm that this is correct, and I won't run into trouble using this many variables? And do variables indeed get cleared when set to zero?
