Annoying bug, i got a weapon unlock at level 36, and i wanted to save it for rank 39 to buy myself the new weapons.
Today i logged in and it just disappeared...
What can i do?

Hey... I have the same problem.... and the bad news:

There is nothing you can do..

I tried to contact an Admin to get this fixed:
- postet in the Forum
- Wrote to the Support
- pvssyd in EA Livechat

There was no reaction at all.

Next unlock is at level 40 I guess so u have to wait until you are 40 and when u are 50 there will be still a Locked Weapon.
