It seems to be a stupid bug. We need masternodes to update to a patched version for the chain to move (it's not my lucky day today). Also I don't know what I'm doing. There might be some other problems with reserve payments.

Here's my quick fix

Also I saw 3 attempts to propagate blocks with correct rewards in debug.log. So it's possible that someone has moved ahead.
