After the "bump" incident I carefully loosened all the spokes, checked for flat and round. Replaced the 1 non ds spoke and trued the wheel and re-tensioned the spokes with a meter. The wheel has zero dish (I swapped spacers to center the hub).
The spoke a week ago was a pulling spoke also non ds, about 45 degrees from the other.
Of the 2 yesterday 1 is again non ds, about 45 degrees from the other 2, all 3 are in a 90 degree area of the rim. The other spoke is a ds pulling spoke about centered 180 degrees rotation from the others.
