Full Arsenal Broken

[illuminati1556]

 

I've been playing B&T and I'm so close to the platinum.  I just finished the final mission I needed to get 5 stars on to get Full Arsenal. However, it did not pop. I have every collectible, every marksman target, and every mission 5 star. Am I missing something or am I SOL? 

I am noticing my game is super buggy when I go to the loadout screen. I can only equip the mods for 1 of my two weapons. If I put it on the mount, put it away, and then put it back all my mods are unequipped and floating in the air... invisible.  I just have to grab around until it looks like I'm holding something. I think I'm also missing several paints despite getting 100% on everything. I have no idea if this is screwing up the tracking for unlocking everything. 

 

Please, any help would be appreciated.
