Weapon skills not progressing

[Equal]

been a few updates since i noticed this problem and nothing i can see has solved it.
i can see no movement on some of my weapons progression bars over several days.. if there is any progression on the weapons ive kept track of, it reverts back as soon as you switch to your backup weapon and back.
ive also noticed that all weapons classes this occurs with only happens when they weapon itself is maxed out. ie. as soon as you switch to a brand new assault rifle, then assault rifle levels go up again.

no sure if this is a common problem, the search function on this forum hates me

I've noticed this as well, I use my LMG 80% of the time and my skill level is stuck between four and five but my pistols, shotguns, etc level normally

From what i've been lead to believe once a weapon is maxed out and gains its bonus stat it can no longer be used towards that weapons proficiency. Which is why you see so many threads complaining about this. Some people are lucky enough to have a bug where they can keep gaining proficiency levels after maxing out a weapon.

This is a true statement. Weapons reach a max exp and that's it. You can go into your inventory and look at the weapon where it shows stats will show its exp.
