Bigger Crafting Tables is a very nice mod for modpack authors that wish to have bigger crafting tables for more complex recipes. However, the fact that the tables keep their contents completely breaks the balance of more difficult packs, as you can basically use them as backpacks. This mod is a fork of Bigger Crafting Tables that fixes this issue.
For now, the contents of the tables just get deleted when broken, as this is more of a hotfix for aforementioned balancing issue. At some point I might look into making them actually drop their contents when broken.
It's also not out of the question that at some point in the future I will add more features to this mod, like for example an even bigger 11x11 crafting table, but I can't guarantee anything.
