This server is 1.9, and bone blocks are 1.10. Unfortunately, until they update the server, we do not have access to the bone block. Though this would be cool to do once we update.
I believe they will revamp maps once we have access to new blocks once they update. They did it to the end map with the chorus fruit and purpur blocks.Lock please but could you forward this to @Tacosbefriends so he know for future refrence...
