Gravimag bug

[(PSN)MTV_Ninja05]

Upon purchasing the Gravimag for 20 platinum from the Arsenal, Archwing tab, I have one weapon that is now in my Heavy Weapon slot (I also purchased the Exilus Adapter) yet I had no Archgun deployment item nor Gravimag item in my Gear. 

When checking the Foundry, the Gravimag blueprint I had bought long before was still there, but there was no indication I owned it, even though I went from 80p before to 40p (20 platinum per Exilus Adapter & the Gravimag.)

Upon checking the market finally & purchasing it again, I'm now at 20 platinum & the game has actually registered I have purchased it.

Steps I took: 

Go to the Arsenal on your Orbiter.

Tab to the Archwing tab.

Through Heavy Weapon, purchase the Exilus Adapter, & then also the Gravimag.

Even after logging out & back in, the Heavy Weapon the Exilus Adapter was used on is available to customize & shows in the characters' hands, yet the Gravimag will not be in your inventory.
