Crazy Idea, and maybe I should make my own thread for it, But instead of tracking coins, could the game instead track transactions?
Dwarves don't have debit cards. I understand that the coin system, as it was, didn't work that well, but if dwarves were able to carry a significant amount coins on their person and if a single bin could hold 100,000 coins or some other large number, it could work quite well.
Also, minting coins doesn't have to be necessary to use them if the coinage of the mountainhome can be obtained by trading with the dwarves.
Problem wasn't number of coins, it was stacks. The problem persists, in adventure mode. buy and sell things a few times, see what happens.
And while they don't have debit cards, they do have purses... if the purse has a "balance", and just tracks transactions, the only time you'd need to deal with stacks of coins is when they were minted.
