Invisible chest and furnace

earlier today (12/17/19) i encountered a bug that made chests and furnaces invisible and unable to open. Originally I thought it was a bug with my world not loading everything up because I was playing with someone else far away but when I left and joined again the chests still weren’t there nor able to be opened. I had 20 diamonds lots of iron emeralds saddles wither skulls and soul and gold but now there all gone even if I break the chest (which and break even if there invisible) none of my items would drop down onto the floor. But I hope someone sees this and can give me advice or something like that
