Money breaks at 2^31

I assuming someone reported it by now, but the game money cap is 2^31, and odd things happen once you pass it.

When i logged in i has 0 money, i build something and it change to 1.5b (fair below what i should have). I assume the database value keep overflowing contently all this time, meaning at some point i would of been at NEGATIVE 2b… wounder what would of happened then
