Looks to be similar to the bug that was fixed in 18w02, though I didnt see that when typing in "Zombie Horse Invisible" for anything recent. The log data seems to indicate a rendering issue:

confirmed 18w07b on a map I exited with crafting table open.
here is the log portion of the crash:

Also, the blocks are solid and remain that unless broken by hand or the machine is turned back on. If the machine is turned on they disappear until you stop it, and it bugs out again. It is not something that happens every single time, but about every 5th-6th switch.
Oddly it allowed me to attach the screen captures after I posted..
