(03:11:48) | Error while compiling: ZoneManager.cs(1343,64): error CS1061: Type `SearchLight' does not contain a definition for `fuelType' and no extension method `fuelType' of type `SearchLight' could be found. Are you missing an assembly reference?

I'm still relatively new to ...everything Oxide has to offer, however this error popped up when trying to load my plugin.  What exactly does this mean?  Is this due to SearchLights now requiring electricity or something?
