For some reason it didnt remove the teleports from last wipe this week.

Now people are under the map. What is suddenly causing this bug?

Ah solved it by settinb forceontop of foundation. Only downside is peoeple cant set teleports on upper floors but oh well.

All you do is read the plugin documentation and see the Admin chat command /home wipe - Removes all homes. and the problem is solved, The plugin is not set to remove the homes after a wipe , As the admin (who stops and starts the server) you have the opportunity of typing that command in chat before anyone else joins or go to NTeleportationHome.json, and depending on your setup the NTeleportationTown.json file and delete all the information in them, if you dont want to join the server,
BUT make sure you delete the data (*not the files) before you start the server, Data files dont always save changes if the plugin is loaded or the server is running,

I tried at one point to have it automatically wipe on a new version.  But as users of JPipes can likely attest, that can pose some issues.

It works great, people just have to read the documentation for plugins, most of their problems can be solved by just sitting there and reading for a few minutes,
