There are, unfortunately, a number of issues related to "extresist" that I have been attempting to work through. Currently it fails for capacitors, bipolars, and diodes. And its behavior with respect to hiearchy is not well defined, which means that your best option is to flatten the entire circuit before doing an R-C extraction.
