Good news. I updated the server to 1.13.1
Bad news. Essentials hasnt updated so for now there will be no way to get back to spawn or set homes. You can still however, use your bed as a respawn point.
Other changes include the addition of grief prevention and a different tree chopping plugin (other one didnt update). Also the ranks have been added back but you don't get them automatically. You can ask me or poptart if you want your rank back.
Edit - Added plugin Gwarp to add the functionality of warps and homes. To set a home do the command /home set (name) and to go to it you can do the command /home (name)
