(Help) Stamina issue when sprinting with weapon drawn and light armor

[AmnesyaLy]

Hello I seem to ran into my weirdiest bug yet..

So in short, when I sprint with light armor equiped and weapon drawn, I don't consume any stamina.
However if I sheath the weapon, or remove all light armor (keyword) equipement, I will consume stamina normaly.

I've tried disabling the latest mods I installed since this bug appeared and going back to clean save, can't find the culprit. The only one I did not desactivate was FNIS because I doubt it could be it's fault and configuring it with my modlist and nemesis take to much time..
I've also checked all my mods for every PerkStaminaRegen and nothing seems to override Skyrime and USEP. I don't know what other name could be use for similar behavior however;

 

At the moment I made a band-aid using this mod: https://www.nexusmods.com/skyrimspecialedition/mods/85735 which doesn't fix anything unless I add an effect to spell based on "WornApparelHasKeywordCount" for "ArmorLight" => 1 and IsWeaponMagicOut => 1, but first it's a very ugly fix and second the consuming isn't close as it should be until I find a better value :/ (I've set it at 14 at the moment)

 

What is certain is that somewhere there is something applying an extra stamina regen for each "WornApparelHasKeywordCount" "ArmorLight" when IsWeaponMagicOut = 1 (I tried with only 1/2/3 item of the set and what I found is that a really tiny drain is applied if I equip only 1 ArmorLight equipment), or it might nulify the stamina drained somehow, tho there's still a tiny little drain if I wear only 1 piece of equipment...

Would anyone have any clue to how I could find the culprit and fix this issue? :/

 

Cheers.
