Well sorry for the late getting back to this but I've had a dig through the mod and a load of testing and it works fine on my system. Something on your end must've been causing it. Try unsubbing/resubbing or w/e I guess, not sure how else I can help when I can't repeat the problem.

I switched to green and it worked, and it def was checked on.

Works fine on my end, try validating game files, unsubbing/resubbing, making sure it's ticked in mod manager and it's not being overwritten by another mod by dragging higher in the load order etc. etc.

I installed it and activated it and it didn't change. I am unsubbing and trying the green now.

Yeah working on it, just in testing phase since LL reskin stuff.

Will you be able to change Hellebron faction colour to red?

Yeah turns out this update broke every single on of my mods lol. Same issue, same fix, uploading patch currently.

Just to let you know, both this and the Sartosa mod are causing the game to crash to desktop on launch. Don't know if any of the others are doing the same,
