Yesterday, the new Steem code had another "gotcha": this time in code related to the new 'mildly non-linear curation curve'. The error took longer to debug than the previous bugs, but Steemit engineers published a patch to fix the bug, and witnesses are now running with the corrected code.
However, due to the sheer amount of data in the Steem blockchain (it's one of the busiest blockchains out there), it has taken a while for the API nodes like our wallet node to replay the data. However, we've finally replayed at this point and we can process Steem transactions again.
Note that if you made a sale or purchase via our site during the down time, we've automatically processed any transactions that happened while our wallet was down.
