I'm in the same boat as Kimon B. Selfhosted Bedrock Server 1.14.60 with invisible chests. I started playing a brand new world a month ago on 1.14.60 client and server version. It seemed to have broken all the chests in a certain area. Chests, hoppers and furnaces that are 15 blocks away didn't get messed up, but all the chests in a small area did. All that is left are wire-frame boxes where the chests should be. I tested breaking one and it just gave me a chest and none of the contents.
