Bug/Issue Access violation, planet with builds no longer accessible

https://pastebin.com/qp7qteDn

This happened fairly recently. I go down to a certain place on my favorite hunting planet in my favorite spot and the game throws this error message and the game closes.

EDIT: The first time this happened, it said it tried to load a nonexistent "Material 32512". Now I know this isn't in the vanilla game, and I meticulously dissected all my old versions of mods looking for it. Subsequent iterations of this error throw the radiantLight error above. I cannot find this material anywhere. I did once solve a duplicate asset error between the Munari mod and FU, where two blocks had different IDs, but the same name. It did this then, too. I just can't find it anywhere. It looks at first glance like one of Elithian's, but it's too far out of its maximum range.
