I bought 8 skelly spawners from the shop in Halifax. When I placed them in my grinder the first two went from skelly to pig. I mined the pig spawners and kept them because some day they will make me money when I rebuild that. The other 6 I really want them to stay skelly spawenrs as I now have over 30 pig spawners. I took them to Bob the Fixer and he said they cannot be fixed. I left the skelly spawners in my e-chest. If some one could fix them or replace them that would be great. This bug has affected at least 10 of my skelly spawners now.
