How exactly does the interest rate work? I'm pretty confused.
Also, I think "Random Money" doesn't work if the value is negative and you don't have enough niwas in your pocket to lose. I keep only getting positive amounts, but around half the time I get database errors. I feel like I'm cheating, kinda...
As in, say that the random value is set to -150, so you're supposed to lose 150. But if you have 0 niwas in your pocket, then it won't work, and you won't get -150 niwas.
