I recently got a new K-drive, and I noticed when I was out doing races on Orb Vallis, when I go back inside, it shows "Expired" where it would normally show rank gained. I equipped my old K-drive, and took it out (it wasn't fully leveled), and did two races. While I was out, it showed me maxing the rank. But when I come back into Fortuna and get the mission completion, this is what shows. When I check the arsenal, the rank has levelled up appropriately, so it appears to be a visual issue.
