fastcraft-1.22-ctest8.jar fixes my issue.
Player with the new test build 1.22ctest7 I get a crash loading my home server side not client side
If I remove fastcraft it loads fine
Previous version of fastcraft works fine.
I basically figured out you put items you want to replicate into the scanner, I am just wondering why some items come up error? I mean vanilla blocks like oak wood etc. Is there any way to add other blocks so that they can be replicated?
