-Subject: [PATCH] Update clients when setting blocks to air
-
-In fixing SPIGOT-611, the server sets an area to air and doesn't update the clients.
-Usually this is fine, most of the time we'll just be setting the intended block shortly after anyway.
-
-Except if we're setting air. In which case the server will not send the change because it already sees the block as set.
-We workaround this by telling the server to send the client the block change if it is of ID 0 (Air). I assume this
-patch will not last long enough to warrant moving away from the ID.
