it says weapons not owned when i've been using since the game came out.

Thank you for the post, that's interesting. I can even see the unlocked attachments for your Blurrg from your use before.

Can I check if your other Deluxe content is still available too? Have you passed the 200 kills with any other classes?

Thank you. 

@PANACONDA29 Thank you for the extra info and screenshots, it's odd that it just affects the officer class. 

What has been done about this because i still cant use the weapon.

still doesn't work

What is your issue related to? General
Summarize your bug I purchased the deluxe edition of Star Wars battlefront II a while ago and the additional content included 1 weapon for each class. The FWMB-10K was one of these guns and I used it frequently until it locked itself, I suspect it was when I reached 200 kills (the required amount to unlock the gun). I’m really not asking for much, I just would appreciate it if I could have the weapon unlocked for me again since I paid actual money for the content in the first place.
