hello,
i've come across a code issue in Stronghands and Peerunity that likely exists in PAC,
it will only be an issue where users have more coins than MAX_MONEY (in this case 2 billion).
simply put,
sending 2billion coins (MAX_MONEY) will break your wallet,
it's only the wallet.dat, so if you back up yr keys or wallet.dat, it's good.
if you want to test,
backup your wallet.dat, then send 2 billion coins
then just replace the borken wallet with the back up …..
edit
looks ok for PAC coin.
max_money is 1 trillion, so it becomes a problem when you have more than that in a wallet
also i see the qt is limited to sending 99,999,999
(whereas the SHND wallet allows 9,999,999,999)
