So i found that my weapons skill in assault rifles is not levelling anymore but i found why too
IF you have a weapon you really like equiped (like the EMC gun from episodic missions) and this weapon is maxed up in hiw own level, you won't level anymore in this kind of weapons type.
You'll have to equip another no levelled weapons to continue levelling in this weapon type, tested yesterday night and worked.
So it's quite annoying actually to have an emergency weapons with no mods and no bonus just to continue levelling the weapons type
BTW i found too than the weapon bonus when she's maxed out on herself is changing everytime....
Sometimes is bonus to crit when crouched, sometimes is bonus to close combat etc...
