Due to some unknown reasons, I'm having technical difficulties with the light system and I can't find out why, so I have to scrap it or else the cars won't be able to be released, those issues affects the customization support breaking it completely, and I still coudn't figure out why and it's been like this for months, which made me got unmotivated to keep working on the cars hence why I've been absent these last two months, but I feel that it's not a feature that is used often anyway so I decided it would be best to scrap the lights and make the cars working like they should.
So with that in mind I'm sorry about hyping up with the lights system but I can't release those vehicles with those errors, unless in the future we figure out a way to make it work properly, then I'll update the cars via Blockland Glass with this feature back.
SOLVED! BOTH LIGHTS AND CUSTOM SUPPORT ARE COMING! Thanks Conan!
