We discovered an internal server glitch over weekend that caused some trouble; should be corrected now.
You may need to launch ComicBase and zero out comics you just sold, then post your selling back to AA so your selling database is accurate.
Would it make sense to send out an email to all AA sellers to let them know to do this? If you don't, you run a greater risk of sellers getting orders for comics that they have already sold with the following outcomes: (1) buyers unhappy with the seller and/or their Atomic Avenue experience overall and (2) sellers unhappy with AA and/or ComicBase. Neither of which is desirable IMO.
