(Solved) Custom Entity is Unintentionally Anchored in Place

I've made a custom entity that completely refuses to move by any means. It is not a water or flying entity, and it has no procedures attached, but it is unaffected by both gravity and any attempts at moving it manually, including the velocity override. It can rotate all around the way it should, but anything that would change its position is ineffective or ignored.

Does anyone know what might be happening here?
