When I do a ghost merge in the crypt and I carry the ghost item to the main level, the item is dark, but when I bring the item to the sky bubble, it turns into a normal-lighted item. Why does it do that?
First off, all objects can do that, its just based on the orientation of the object that you are holding. Second, there is a stickied thread created just for helping those among the community who have questions or ideas relating to the glitch. Third, dont reply angrily, im just informing you for the future. I can help you better if you are in the correct thread, and more of the community will be likely to see it there, simply because its stickied.
It's really not a big deal, when the item you're no-clipping duplicates itself, it takes on the lighting effects of the exact point it was duplicated. Sometimes it'll fix it'self as you carry it, other times it won't. However as soon as you put it down and look away from it and/or start a new round it will correct the lighting.
