Had a nice bustling village all decked out, all villager professions represented, lots of beds. Loaded to play about an hour after saving and closing and all the beds are gone in every structure. If I place the cross-hairs on them I can see their wire frames. The villagers can walk on them and appear elevated standing on the invisible beds. They still sleep in them and so can I. If I break them I can see broken pieces flying but when I replace them there is nothing visible (even in the hotbar). If I go into inventory and search beds none of them are visible (but their names do pop up if I hover the mouse over their square and I can choose and place them, but only see the wireframes if I direct the cross-hairs at them). Basically the beds are still there but invisible in game, hotbar, and inventory. I had no other problems or errors and the game did not crash. If I save and reload the world the beds are still invisible. If I refresh the chunks the beds are still invisible.
