The REC shop in-game has not been updated for a while. I can't test the possible loadout of my ship in Arena Commander. Are there any updates to REC you can tell us about?

That should be updated on the PTU right now. I actually went through that myself. That has definitely been checked in. So if it's not there, if you find something that you're missing, let us know. Because as far as I know, I've grabbed everything that should be in-game that's at least available in the PU.
