Hey, i am Level 21 now... unlocked the Marshal and create a class to use it. But every time i get back, the Marshal is locked again and i get my weapon unlock perk back again. I can unlock and use it, but every time i log out and came back, the marshal is still unlocked again!? what can i do... unlocking and unsing the K-Volt did worked fine!

I'm having the same issue with my unlocks. Im level 19 now and through the whole ordeal im unlocking abilities and secondary attachments that seem to disappear randomly half way through the next level. I really am starting to loose my rag with it.

I have unlocked the hammer about 10 times.
The Grendel about 5 times.
I just spent the whole of level 18 with the enhanced movement and then level 19 its gone but i have the option to pick another...
