Whenever the plugin is run with or without being hooked into the mysql database we get this error:
[23:13:10] [Craft Scheduler Thread - 16/ERROR]: Error at SQL INSERT Query: java.sql.SQLException: table pstone_players has no column named uuid

The plugin also causes huge amounts of lag which go away when the server is restarted but will soon come back.

The dev versions should clear that up.

Alright is that available now or are you working on it still?

Pick up the latest promoted (starred) version from my Jenkins. That was fixed a few builds ago.

will do
