This is a reproduceable bug for me re: stock TBM
FSRealistic interferes with the automated checklist process, specifically at BEFORE TAXI → Flight Controls (gets hung up and has to be forced to complete) and also at THROTTLE → Feather Twice (gets hung up and when forced to compllete never returns throttle to Taxi idle).
These items will only happen when FSRealistic (my version 2.2) is connected.
