Hey!
We checked and, unfortunately, You are right. Just two days ago we were happy that there had been no disruptions to the bot but last night there was a connection error to the node that we are connecting to in the steemit blockchain. Even though we had set up a backup bot just in this case, the connection error was not on our side and thus there was nothing we could do. Although the connection was lost only couple of hours, it was enough so that You missed Your daily upvote.
We will send You most of the SBD we have as an apology. Everything is working fine now and we have also tried to mitigate a failsafe in case of another connection error
