M40A5 Second Slot

Some time ago I got a perm M40A5 thanks to a ShopDesc file that was posted here, this one could only be equipped on the first slot. After this 31th content update it should have change from 1 slot to be able to equip on both slots, but my M40A5 can only be equipped on the first slot until now. Should I make a ticket so AE can fix it, or not because they can find out gun was "hacked"? What you guys think?

If you cannot equip it to Slot 2, you've got one with a different ID. You should not contact them, if they aren't full retardet you'll get a ban straight into your face
