Unearthed Fortress Rail Grind

[solid sparrow]

What Happened

Stuck on rail in east side of Unearthed Fortress, character models jerking and spazzing around like a Gmod entity at two specific spots.

What Did You Expect

Smooth rail grinding like I'm playing Tony Hawk's Underground 2.

Additional Notes

See included video.

Exact same experience with this rail yesterday!

Encountered the same thing approaching from the opposite end of the rail, spammed all my keys and it let me off eventually
