Yep, same problem here - ESP balance gone - zero balances. WTF ?

If the guy messed up, he should rollback the trades and deposit the coins back to the wallets.

NovaExchange -
...All trades and such is logged and I could technically do a rollback of all trades even if it will take a lot of time to sort everything out. Which would you prefer?

Jesus, mate, it is pretty clear what you should do isn't it ? Rollback todays trades and sort out the wallet balances. Thanks.
