I tried to rename a crafting table to "Worlds first crafting table" because it was the first one I made and I consider it as a milestone. You might think its stupid, and it kind of is, but that doesn't matter. After I renamed it and placed it back down again, later I picked it back up and it was no longer named "Worlds first crafting table" it was named "Crafting Table" (its original) please fix it if you can.

Blocks are not entities or tile entities, blocks simply do not have the data to store custom names.
