I have been having this problem mostly with the Alpha Jackal not letting me unlock the suppressor attachment for it.

It's all the way leveled up and the suppressor is still locked and my progress bar for it says no more unlocks available for this weapon yet I have seen others using it in game and it's really pissing me off.

I have even Tweeted @Crysis and they said they would look into it but has anyone else had this problem?

Nope, sorry. Wish I had an answer for you.

Got to ask yourself one thing,Why the hell do you want a silencer on a shotgun?

Really?...You must be either A. Troll or B. Not know much about moving silently. Pretty sure it's the former.

Suppressor on a shotgun is not an easy thing to run with but I use suppressors on lots of guns so why not a shotgun?.

Trolling is old already but have fun living in the past.
