When I update my server it works perfectly with one exception... Everyone is stuck in block and cannot really move. We just glitch around inside blocks. Im updating from 1.8 to 1.8.6 I have tried many different snapshots to update to. Whats wrong? I update by downloading the spigot.jar Putting into my jar folder Changing the multicraft jar to run to the same name as the spigot jar Running the server.
