I recently installed openblocks (and its corresponding openblockslib) to my server and the mod items and everything work fine but there are weird things going on. Dragon wing flapping noises are constantly being played around. I have no idea why this is.

Can you explain a little more? I can't understand. Also if you are hearing dragon wing flapping noises, It's a possibility your minecraft files are corrupt, to fix reinstall minecraft in %appdata%.minecraft\versions(the forge version) and then open the install jar file again, if that didn't help, you might want to delete the whole .minecraft folder itself, then use mc launcher again and then type in your password + email, you don't need to tell me it, I would never ask :P
