I popped into my world that had been created since before this newest snapshot and was not able to use the enchantment table properly. I could put items into the enchantment table like normal but I couldn't access any enchantments on the right hand side. Usually, what would happen is you'd put an enchantable item into an enchanting table and you'd see available enchantments on the right side but nothing shows up at all, it remains blank as if I never put an item in in the first place. I've tried new worlds, different pieces of armor, tools, weapons, books, but nothing works. However enchanting through an iron anvil does work with an already enchanted book, and already enchanted items seemed to carry over just fine from the previous snapshot, this leads me to believe that enchanting isn't broken all together it's simply just the enchantment table.
