verifyGeometry violations, Encounter 11

I'm having a strange issue with verifyGeometry in Encounter 11. After routing my design, my tcl script runs 'verifyGeometry' before saving the design (.enc) . 'verifyGeometry' reports that there are multiple violations of various types. However, if I reopen Encounter and load the design (.enc) and rerun 'verifyGeometry', there are no violations detected.

After I save the design (through OA) into one of my Virtuoso libraries, I run Calibre DRC and LVS. The only DRC errors reported are density related. LVS passes.

Does anyone have any idea why verifyGeometry is reporting these violations before closing restarting Encounter?

I noticed that all of the errors involve a "Cell null" or "Pin of Cell null". Does anyone know what this "Cell null" is?

sounds like there might have been an empty module that got cleaned up with the save/reload. hard to tell though.
