Aha! So other people have been having this. I have some bonus screenshots, specifically of the console.

Mine happened with the clone minigun, but it's the same bug described. I happen to have the middle dot on my TFA crosshair, so I can see a little bit of what happens, and what happened was the dynamic recoil parts would just fly off the screen, and shooting like that would cause HORRENDOUS recoil, to the point of either throwing you into the ceiling, or completely destroying your rendering. @Maxwells
