As far as I can tell, our voting bot never saw it (post info was not returned by RPC node, or more likely it was dropped in the process of writing to DB somehow, so the voting script did not know your post existed). We don't have any systematic issue that I can see.

This is nearly impossible to replicate though, and it's hard to do a root cause analysis without replication. Please let us know if you have any more issues, but since it appears to be an anomaly you should be fine.
