Issue Description:

When the ritual diviner of blood magic is used, it displays the location of where it will place blocks. It will accept empty blocks and stuff like grass. So when it tries to replace BOP's grass it will crash the client.

Steps to reproduce:

1. Use ritual diviner a master ritual stone
2. If any BOP's grass is in location where block is supposed to be placed client crashes
