ok. this is pretty stupid of me, and completely my fault.
the system is designed to move cold storage to hot wallet -> then send out refunds.
but apparently the move failed and the script tried to send a bunch of refunds while the input contained no coins...
1000 coins have been moved and script resumed, I'm sure people should see refunds instantly and can vouch. and once I get back on location I can enable more coins to be moved and thus refund resumed.
again, I apologize for the long delay.
