Jail enter and exit points both have a yaw direction now, to set the yaw just use the /jailset command to set up your jail again, or modify the yaw values in the config.
The jail list is now saved to disk every 10 minutes, previously it was only saved when the plugin was disabled or reloaded.
Made the code that checks whether a player's time is up more robust, previously players were getting stuck in jail with times of -30, etc.
