So, I have a Tactical Vulnerability Exploiter MK XII Console - Tactical Zero Point Quantum Chamber
Which is supposed to boost Quantum Projectile
Damage, however the Projectile
weapons Tech Upgrades can't be slotted on the upgrade window.
However, the beam/cannon weapon tech upgrades CAN be slotted on the upgrade window http://i924.photobucket.com/albums/ad81/KaiserKacto/Misc/bug_zps1bae462b.jpg
As you can see on the screencap, I have beam, cannon, and projectile upgrades on my inventory, but only beam/cannon are allowed for this console

In every place,
