So that is the long way of answering "did any transactions get rolled back" (I assume you mean, did double spends occur?) --- no.
"Double spend" is one thing, posting something to the blockchain, seeing that it got posted, and then having it deleted the next day is another. I guess there is no such concept as "unconfirmed transaction" in Steem, a transaction that isn't written to the blockchain in due time is probably lost?
I noticed one of the emergency patches was like "ignore all blocks produced while the blockchain was down", that's part of why I'm asking.
