Solved Gold Bug in Stash?

@Bglzaborg, indeed this has already been reported by another player and appears to be a game limit in multiplayer mode but didn't had the time to look at it yet and see what causes it. Several notes have been sent in game too but most people do not store that much gold in their stash. It seems the gold cap is 33,554,431 even though it's been set to a higher value so avoid adding more gold than that number for now.
If you add more than 33,554,431 gold in stash and then leave the game, your stash gold will reset back to 33,554,431 so keep it under this value and I'll see if there is a way of bypassing this limit.

UPDATE: Found the reason, it's because of the current bits value that the game uses for gold. The limit may be increased even more in the future, until then we will be adding a server side limit so it won't roll-over if you try to add more gold than the current limit is set to. The current value we are using is already ten times more gold than you can originally store per character anyway and should suffice.
