Re: Automated obsidian to diamond creator.
Very nice system, going to make a copy in my world now thanks!
On the trans table issue, you need to delete a file from your save folder for the world in question called tablet.dat.
The file in question will be in your data folder, this file sometimes gets corrupted but doesnt recreate itself so you end up not being able to keep your tablets memory when you quit.
If you delete it, the next time you load your world it will recreate.
