Is there a particular trick to using the grapeshot bombs to destroy the nekker nests in the nekker contract? I used all of my grapeshot bombs on ONE nest and still didn't get a "destroyed" indication. I aimed the bombs using the "R" key and threw the bombs on the illuminated light right down the hole in the center of the nest. Any help would be very appreciated.

Then get out of the way fast ;-)

Btw, any Nekker's alive when the bomb goes off tunnel back underground immediately, so, you can effectively ignore them (on Normal at least).

This works on hard++ too :>.
