This ticket is invalid as it relates to a modded or 3rd party client/server.

• Any non-standard client/server build needs to be taken up with the appropriate team, not Mojang.

• Any plugin issues need to be addressed to the plugin creator.

• This site is for addressing issues related to the base unmodded MineCraft.

Deleted the folder .minecraft Opened the launcher and redid the tests on different servers from the first.
