Inconsistent simulation results

Today I encountered unexpected behavior with carbide create. The simulation demonstrates inconsistent paths depending upon the type of cut (inside, outside, zero, and pocket). Please see attached screen grabs. Any thoughts? Photos here(as a new poster I am limited to only 1 image here).

The previews are being affected by an optimization pass which discards small features, incorrectly in this case. You can see the actual toolpaths indicated by the blue lines in the Toolpath view, or you can use a 3rd party viewer such as Camotics.
