Rider will not stand up on bike

[Copper]

So, sometime after the most recent patch I have become unable to stand on the bike. He will stand briefly in the air, but the animation clips, so as soon as the bike touches the ground again the rider goes back to sitting.

I have done a fresh re-install twice, deleted all mods, renamed mod folders, and changed my settings, to no avail, so I am unsure of how to solve it.
