Interesting 787 Airworthiness Directive
Software issues....
This AD is effective March 22, 2019.
We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 787 series airplanes. This AD was prompted by a report of an uncommanded descent and turn that occurred after an inflight switch to the spare flight management function (FMF). This AD requires an inspection of the flight management system (FMS) to determine if certain operational program software (OPS) is installed and installation of new FMS OPS and a software check if necessary. For certain airplanes, this AD also requires concurrent actions. We are issuing this AD to address the unsafe condition on these products.

... and the pilots just did ye olde "Aviate, Navigate, Communicate thing" so nothing untoward happened and no headlines were made.
For that part of society that happily awaits the future of airliners without pilots, it was a bleak day.

uncommanded functions by the FMS are a bit more than the ANC thing.

As you say,with the Fire Switch bulletin still current..the descend and turn manoeuvre may be highly appropriate!!!
