when you have or go up to 2147m you can still receive gold in trade or duel and instead of going to the bank. so when i accepted 5b for 3 phats he offered 2b and 3m plat tokens Ididn't realize i already had my cash in my invo it still accepted and i still only had max cash and tokens and no stack in bank. Hopefully this gets fixed so others don't run into this issue.
