Overflow detected when using addition on the two values, 2147483647 and 21474836. As Wikipedia explains overflow: Arithmetic overflow, a condition that occurs when a calculation produces a result that is greater than what a given register can store or represent With the first value being the greatest positive value a signed integer can store, the result of the addition is greater then what a signed integer can store. My guess is that when the script calculates the interest, it doesn't check if the value will overflow or not. I don't remember how the emulator works with overflowing values, but do you get a negative bank value if you deposit more money?
