In this new version of RandomTPItem, I have added the ability to prevent players from being teleported into a faction's claimed land by a "RandomTP Item" (This includes Safezone and Warzone areas). I have tested this new feature out plently of times and have not been teleported into any claimed faction land (including Safezone and Warzone areas).
Note: This feature requires that you use the latest versions of Factions and MassiveCore. However, there is a configurable option to enabled/disable the use of Factions/MassiveCore if you do not wish to use it on your server!
I will update the resource page with the appropriate link to Factions/MassiveCore, update the features list, and update to the most-recent configuration.
