This bug might or might not exist still, but nothing in the changelog mentioned fixing it.
This is with version 1.13 on both client and server, on a little lanserver (hosted using dedicated server though) I was running (I have a spare computer that I don't use so I host a server to get better framerate) and I got kicked with an "internal server error". The server's log showed this:
And the client log had nothing out of the ordinary.
Edit: Just wanted to mention, all it did was boot me and then I was able to rejoin just fine afterwards. I was mining coal at the time, although it did have a mostly-broken ghostblock of the coal I had mined for ~10 seconds after I rejoined.
Edit2: It's happening multiple times, always with the same error, anywhere from 10 minutes apart to several hours apart.
Edit3: I wanted to mention, for some reason your blocks are generating as if they were ores.
