The ring appears fine without changing the save you posted. Is that what you mean? Are you still having the issue? Do the crashes still happen if you temporarily remove Advanced Location Loader, Animal Husbandry, Custom Farming Redux, Custom Furniture, Custom Furniture Anywhere, PyTK, SpaceCore, and Stack Everything? Unfortunately that error doesn't have much info. Does it still happen if you remove all your mods temporarily? If not, try putting them back one at a time to figure out which mod is causing it.
