Test was first failing at line 166, then I fixed it and it is now passing but code coverage is not properly updated. (run impacted test auto engine mode).
If rerunning test explicitly within existing task runner it get covered.
I also noticed previously the closing bracket "}" was indicating not covered even though method was not throwing and rest of method was covered (which was somewhat annoying because I could not get it to become covered in NCrunch). Have no screenshot of that atm though.
*edit: submitted bug report with title "missing coverage"
