+>>> Indeed, I know the problem; I ran into the same kind of thing with my [[plugins/contrib/report]] plugin and its `trail` concept.
+>>> I simply had to declare that one couldn't use "trail" and "maketrail" options within the same report. That way, "maketrail" will add links in the "scan" pass, and "trail" will test for links in the "build" pass.  That usually works. --[[KathrynAndersen]]
