A radical drop in pitch from A440 after a pitch raise and tuning in a short
period of time is certainly one excellent indication of some structural
problem, and would be an excellent signal to start searching for the place
of weakness.

One such grand piano did that to me, pretty much is the same fashion as you
described happened to you, except it only took three weeks to drop back to
where it was on the first visit.
