GLITCH:
The Rider's shadow has an extra pointy section that moves completely different from the rest (Spinning & Stretching).


CAUSE:
Equipping your rider with the E.S. Enforcer Bottoms 2. (Took my weeks to find this)


SORT OF FIX:
Just don't use the E.S. Enforcer Bottoms 2, I switched back to Bottoms 1 even though I like the 2nd ones better.

COMPARISON:
E.S. Enforcer Bottoms 2 WITH shadow glitch.


E.S. Enforcer Bottoms 1 WITHOUT shadow glitch.


EXTRA INFO:
Found on Xbox 360 version.
Saved replays will obviously still feature the glitch.
Don't know if this happens with Bottoms 3 as I haven't unlocked them yet.
My first post, so sorry if this has been mentioned before (tried the search).
