Great! Thanks for refunding it.

"...as far as I can tell it was a node issue with Jussi."

Does this mean it's still possible that this might happen again?

We don't use the stock nodes, I was testing it for a short time but it just causes too many problems. A lot of bot owners (not just bid bids) have been complaining about errors related to Jussi.

Jussi is a caching layer Steemit Inc built that sits on top of the full nodes to optimize response time, but it still isn't stable yet.
