There is an error with the STF Store. I click on the Armor Requistion and ended up getting the Weapon Requistion instead. Branflakes witnessed the event happen and thinks it was likely a bug as well and not player error.
What gets me it took a month of saving EDCs to buy them.
Another "bug" in that store, is the ground weapons shows no Antiproton split beam rifle, and something else, and they have like 3+ pulsewave assault or w/e's in there. Hoping this is not intended, and if needed, I'll go in game and double check the exact items missing, and the exact item. BTW this was pre 3/2/2012 patch, so I haven't been to DS9 to check again.
