I don't recall anyone else reporting this problem....

There is a followup post in the hex editing topic with the heading 'Summoning Doll Unused Levels and Skill Points' (here) which describes how to edit those attributes (never tried the range or respawn duration skills).

Hex editing - gold, experience, stat/skill points

You could also just give your DK an extra 12 skill points, and re-invest them into the summoning doll upgrades.


Hex editing is not really that much more complicated then text editing, once you get used to the hex notation. Unlike surgery, you can screw up as many times as you need to in order to get the hang of it, as long as you backup the file and/or save folder first.
