Included in the images below, a huge problem in the new beta is invisible blocks. This happens on single player and multiplayer worlds in the new beta. It effects every block, most commonly, crops, Stone, dirt, ice, and it can be replicated with all other blocks. It happens whenever you mine or destroy a bunch of blocks in quick succession and it happened quite frequently. The amount of blocks that turn invisible are crazy. Once they’re invisible, it takes a block update or reloading the word for them to reappear, however before the world is reloaded, you can move through the blocks (taking suffocation damage) and the blocks effect entities too. The images below are before and after reloading the world after mining. The best way to replicate this bug is being able to mine as fast as possible, such as efficiency 5 or haste or heart of the sea effects. The most success is on a word that you have joined, however it can be done on single player worlds quite often.
