Minecraft 1.8 Adventure Map

I have a server but it's glitching up right now...
I'll try and fix it...
The IP is 5.49.13.105 and it is a Hamachi server.
You can download it here: https://secure.logmein.com/hamachi/ih1.asp?lang=uk&c=t4o1itw8ubwp3r7yb7iv1e4m18quxxyt3s5ymg3l
Oh, and if anybody nows how to fix the glitch, this is what my server says: 151 recipes
16 achievements
