It is possible to retrieve object via nearestObject[s] commands. Next step - use reveal command for retrieved object. After that cursorTarget returns correct object.

My workaround script:

_curTarget = cursorTarget;
if (isNull _curTarget) then {

_nearestProblemHouses = nearestObjects [player, ["Land_i_House_Small_03_V1_F"], 20];
{
  player reveal _x;
} forEach _nearestProblemHouses;
_curTarget = cursorTarget;

};

PS: 'nearestBuilding' command also don't see buggy objects.
