So I was making a cave for myself, and I decided to use dead coral blocks, one of the new 1.13 blocks added. I was digging dirt with a legendary shovel (Auto-mine shovel), and the coral blocks glitched and disappeared. If I placed a block in the spot where the coral was it would return to coral. However this happens with the coral blocks that are about 10 blocks in radius of the player, they all disappear. Could someone please check up on this? Thanks.
