[MC-57470] Crash loading world containing blocks with removed data values: java.lang.IllegalArgumentException: Cannot set property

When any client goes to one specific area of the world, the server crashes with an exception (see crash report). No idea what block causes this, but the exception is the exact same as the one I reported for chests in client (and I have since replaced all chests with air using mIDas so there are no chests in the world anymore).

Description: Exception ticking world
java.lang.IllegalArgumentException: Cannot set property ayj{name=facing, clazz=class dt, values=[north, south, west, east]} to down, it is not an allowed value
