K-Drive problems. Again.

[Raydge]

So what's up with the K-Drive in the Equipment screen? I've maxed all 3 boards, but the icon still displays it as "Unranked" with 0 xp, usage, kills et cetera. I don't know whether I got the xp at all, since I wasn't keeping track (please tell me I have taken it, don't want to go through the nightmare of maxing more of these) I have not used a forma on any of the boards I maxed, it's their first leveling (please tell me I don't have to forma them once for it to count) Is this really a bug? Or am I missing something?
