Since never. This balance business has happened a couple of times before and in those cases was corrected within a day or so. My guess is that it's some monthly processing that didn't get done because of the holiday. Too much merry-making in New York?
I might note that my 123rf revenues were misreported yesterday, with the rate based on level 1 (I'm level 5) and the credit total still showing December's figure. Both were fixed when I checked this morning. Annoying but not harmful, as is the problem at Shutterstock.
