Permanent accuracy loss glitch?

I seem to have run into an issue when playing for prolonged periods of time.

Basically, it seems that the longer I play, the more my accuracy drops, and the recoil goes through the roof. It starts fairly insignificant and eventually gets to the point where I can’t use Hyperion guns at all because the bullets go all over the place and all other guns are awkward to use as well. The glitch only goes away upon saving and quitting.

I feel like it might be related either to Surprised? Stabilize! or the Mechromancer Action Package (I’m also sure it can’t be Drop the Hammer, as I did not spec into the skill when the glitch started happening). Any help would be appreciated.
