Glitch with Protection Stones possibly?

It happens once in a while, but where I have a glass enclosed area with PS Coals right next to it appears floating glass that is unbreakable and sometimes flickers.

Try relogging, chances are it's only client side.

K, thanks. It works, but it gets annoying. It does it once in a while.

It's most likely a bug with the plugin conflicting with the new minecraft version.  I'm sure the plugin developers will update it in the future and resolve the issue.  Until then probably just ignore it xD
