Colliseum Armor is broken

The Colliseum MTX Armour currently does not look as advertised, and shows in nearly every situation as a dark brown-black armour.

Applying character effects, for example the Scavenger Character Effect, shows clearly that currently some shading is borked on the armour.

I do not have similar problems with the visuals of any of my others armour MTX.

Please fix this. Thanks.
