Gravestone Signs and Teeth placed in your condo will not network properly to visiting players, this likely has to do with them having variations.
Steps to Reproduce
1 - Have someone else in your condo
2 - place down a Tooth or Gravestone Sign
3 - Edit it as much as you like, only to find that your friends cannot see it.
Notes / Media
Note: this may affect earlier items with variations currently but I didn’t test them.
