Finally got around to setting up a Google Cloud Engine for extracting some of the bigger designs (my mac couldn't handle almost all the mpw-1 designs). I just ran device level LVS on some of the submodules of mpw-1 that previously passed, but now the top level of the extracted netlist is not wrapped in a subcircuit definition and fails LVS.
I logged an issue. Checked the commit messages for the last few months and skimmed the manual, but no clue. Do you have any ideas?
