it seems that the upgrade to HF21 is causing us a bunch of problems and many of our transactions are not working properly.
Overnight steem-bounty and the vote club are not working properly due to the fact that we are getting a bunch of API errors, that seem to be caused by the upgrade of witnesses to HF21.
As a result please stop using steem-bounty.
We will make a determination if and how we will continue with the service.
Sorry about this inconvenience.
