There were some bugs with the duty system and the invulnerability of the jailed players. There is an automaic Debugger to help you detect errors caused by the bugs of the previous version of JailStickGO.
-added command /jdebug [player] (permission: jailstick.admin )
-now you can chose if making the jailed players invulnerable or not (from the config.yml file).
You have to delete the old folder of JailStickGO, remember to save your configuration and jaillocation.yml values in a picture or in a notepad.
you can copy-paste the jaillocation.yml conents in the new jaillocation.yml file (or set the jail and leave location again in game) then you can recompile the new config.yml file.
hope you enjoy the new version
