Hello
Do you have some sort of graphics mod loaded? The error is coming from the part where it modifies the centrifuge's light mask.

That's because of Bluetonium then, that mod has a dependency of another one Tintrifuge than changes centrifuge's colors.
In 2.0 I was using the same mods but with the original Atan's mod, didn't have this error.

Thanks for the info. Since Tintrifuge does what the offending code was doing anyway, I replaced it with a dependency. It should be fixed now.
