OK, I think I see what you want. You want to have the ESP charges at the coordinates represented by the Bqs. This is not the way this should be done. Bq's are considered to be charges and there is a charge expected to go with it. Without a real charge there the code gets confused. However, there is an alternative: Replace bq with X.

H -1.6444 1.259 0.3632
X -0.67775 0.8705 -0.1816
X -1.3167 0.93965 0.22295

This should work. Please post the full input deck.

This one.
It sounds that for MP2 "bq" is a point in the space, but DFT requires an element.
