Me and My friend are trying to set up a server for MeC. We can both craft scaffolding in SSP then we try to in our server and it will pull it up then delete it and show us it in the crafting box again. My friend is hosting the server and has tried installing the mod 3 times and tried using it with and without META-INF. Were stumped and couldn't find our answer anywhere else. Used search to double check but couldn't find any answer.
