This has happened to me with a number of things, most prominently the first shotgun, the Jackal, and the Flashbang grenade -- the Jackal has only two attachments of three unlocked, although I have received three tokens with no way to get more, and the Flashbang has been unlocked and then re-locked again.
Jackal unlock issues: 2 unlocks where 3 should be awarded
What the developers need to do is relatively simple; run a check on the number of unlocks that should have been awarded (based on the level of the item) and compare it to the number of unlock tokens plus the number of unlocked attachments / weapons. If the number of unlocks spent + saved is less than the number awarded, then additional unlock tokens should be granted.
As this apparently has not happened with the release of the 1.9 patch, would it be possible for my account to be reset? This way I can attain the missing unlocks, although I will have to redo ten levels of play. If not, when can I expect the problem of the missing unlocks to be fully resolved?
I have contacted EA and Crytek support on multiple occasions but EA refer me to Crytek, and Crytek do not reply to messages sent from their support page. Please help me.
