So I got the one for "free" from T-bug, and am trying to buy more. Trying to buy any of the green ones, in fact. It takes my money. It sometimes very slowly on the left shows item received. But they never actually appear in my inventory.

If I buy just a single green, it gives me the grey ping as the "item received"

edit: actually, these are very cheap hacks from yoko with this issue, like $600 a pop. These cheapies don't show in her filtered shop. Really weird.

edit2: I am an idiot, these are just the blueprints.
