Series C Black Boxes
 

All of the clockwork spiders in Ak'Anon for the quest Series C Black Boxes that you are supposed to give Shiny Cards to return the exact same Blackbox XIIC. Each one is supposed to be different, corresponding to the name of the spider:

Clockwork XIIC should return Blackbox XIIC
Clockwork XVIIC should return Blackbox XVIIC
Clockwork XXVIC should return Blackbox XXVIC
Clockwork XXVIIC should return Blackbox XXVIIC

It is currently written to provide different blackboxes. If that is not working at the moment on the pve/pvp servers, it was changed since the last patch.

Fixed, pending update

Just in case this matters, OP in other posts stated he wasn't using titanium client on p99 and was getting SQL errors when selling FS weapons. Not sure if that affected the black box reward he was getting. I never verified in game myself.

After reviewing other posts, I don't think he was playing on p99.
