Hello, Waterfall. You have GlueBone set to 0, it should be 1.
Literally, "glue to bone," in such variables with 0 and 1, the game usually reads zero as false - incorrect, and 1 as true - correct.
Therefore, GlueBone 1 is read as "glue to bone - correct."
If some creature you were looking at had GlueToBone set to 0, it means that the effect of that creature is not attached to the bone. Necrodrakes seem to have this issue; it looks like the eyes are hanging on the skull's bone, but in reality, they simply move independently, just like the skull. But I'm not sure.
Good luck with the mod; it's great to see that you're not abandoning it!
