We have found that balances on some older accounts look significantly incorrect when compared with the old database. At this time we do not know what caused the balances to be off, or how many of the older accounts are affected. We haven't touched the old backend or database, so we're going to import the accounts again once we have found what caused the off-balances.
Translation = It is irreversibly fucked up and we have no idea what to do. So we are going to make up some numbers. Add a little here, take a little there. There we go....doesn't look so "significantly incorrect" now!
