Hi Hive account@fitinfun, I've investigated the vote logs for your account. Looks like the majority of the "failed votes" are false positives from the blockchain after the broadcast, so your vote is still on that article in most cases.

I've also investigated the vote logs for your supporters (that use Steemdunk), I see nothing out of the ordinary except what was stated above. For some, the daily limit has been exceeded according to their settings they configured.
