technically this is not a bug
XR use same UVmapping from headlight and reverse light
you just edit the default texture of the game
technically you're a bug
now i understand your error, i never see it, only bug (i know) in some time the UF don't load all textures from model, all lights/interior parts looks white for me, to solve i just enter in the garage and select UF
Demo user using s2 content... Seems legit...
I would like to suggest Scawen to update the local network too. I think it should be more secure too or if not then remove it (not a good idea because some players can't join their servers without it, so better make it harder to crack).
