first-person weapon animations randomly slow to a crawl

[Bunslinger]

video is a little dark, but hopefully it's not too hard to see what i'm saying

 

so basically, every so often, weapon animations will slow to a crawl like this. they're basically playing at the lowest possible speed, and I don't know exactly what's causing it, and google nor FO4Edit is any help. this persists until i open the pip-boy, or, as mysteriously shown in the video, it looks like the effect has a duration, as it wears off eventually without me doing anything. but again, I don't know what's causing it, no chems or anything were taken beforehand.

 

something i've recently noticed, though, i feel like i can reproduce it by sneaking, though i don't know by doing what while sneaking, it's just i was clearing out augustus safehouse earlier and using stealth to clear the area, and it happened at least 3 times during that run.

 

i'll post my load order if necessary, but i'm hoping someone else has had this issue and knows what it is already.

 

EDIT: after some testing, i feel like i can at least confirm for certain it has to do with crouching somehow. i've been sneaking a lot less lately and it rarely happens. crouched to loot a super mutant once and it happened again almost immediately, but wore off pretty quickly.

I believe I've discovered the culprit: Automatically Lowered Weapons got an update a couple months after the last time I downloaded it (which was apparently may of 2017, the update was august 2017), and this update added an animation speed multiplier "fix" which I assume misses its conditions every once in a while so it ends up persisting even when the conditions aren't met. Removing any trace of the fix effect, while it brings back the issue of animations playing at normal speed regardless of your current movespeed, so far has not caused the issue in the video again.
