UPDATE: As of this morning the problem seems to have been fixed! At least for me in this group. (I didn't have deviations in my other groups to check them)
If you are still having the issue with your own group— to get around it the easiest way I've found is to vote on the top submission, delete it, then refresh the page and repeat. It's a pain in the butt, but it works and is easier then re-submitting the deviations and better than blindly accepting them. (or so that's my opinion lol)
So I’ve noticed a strange issue dA has apparently been having (unless it’s just me?). When I go to approve/deny your gallery submissions it lists every single submission as being submitted to the same folder as whichever is the first in the messages— so I may have accidentally denied some of your deviations thinking you submitted to the wrong folders.
If this happened to you, I apologize and please feel free to re-submit your work to the group. I found a way around it (approve/deny top then refresh the page) so I’ll be able to see where you’re submitting from now on.
