Anyone who gets an error, when loading the new 1.7.7 version after forcewipe, similar to the following :

[NTeleportation] TPT datafile: Newtonsoft.Json.JsonSerializationException: Cannot deserialize the current JSON object........

Just reload your plugin via

o.reload NTeleportation

and it should fix the issue. It occurs because the same data file/name for the data file is being used but instead of storing a List, it now stores a Dictionary. This error is harmless and actually sort of helpful since after having the error and reloading the plugin, it will clear the file and start fresh.

If you happen to see this prior to updating to the newest version (1.7.7), feel free to delete the file yourself from the data folder, its called "NTeleportationTPT.json".
