Tabulate Areas 2 tool not analyzing overlapping polygons

Discussion created by pfroemke on May 2, 2014
I'm trying to calculate landcover areas on a polygon layer with nested (overlapping) polygons. Tabulate Areas 2 produces results for only about half of the polygons. Seems like every time I run it, I get a different set of results. The first run was missing 1 or 2 records, the next was missing 18 records, and this final one is missing 25 out of the 51 polygons.
I'm stumped. This tool seems to be working quite randomly.
Any help is appreciated!
