Nice, worked for me too. Have had 2019.16.3.2 since 01/06 and it had been ok (apart from TACC/AP wanting to kill me or have so much phantom breaking that I gave up using it for a while as too many near rear ends) but today also noticed no lane lines or vehicles around me and no TACC/AP so turned off Sentry and after a while it was back. I did end up powering off anyway and also cleared the Trip A and B (even if for placebo effect - who knows if it actually does anything) but all ok now.
