Ideal For
Optional Addon - PlotSquared Integration
For servers using PlotSquared, an optional addon is included that links the generator system directly to plot ownership.
This version ensures that generators respect plot boundaries and ownership rules, allowing safe generator use in shared or regioned environments.
Installation is simple - drop in the addon version, and it will automatically adapt to PlotSquared handling.
