Stuck with a turtle, Karrakh, and Magic Valley

[King Kong]

After speaking with the ork shaman and having the big-ass turtle have his/her magic crystal back, my character is transferred few steps towards West: right in the middle of hills! At this point I should get my crystals as reward, alas! I cannot retrieve them because I am immobile in the middle of stonewall. Any suggestions? I tried to google for a map-switching cheat or similar tweak, but came up empty-handed. At this point, I cant complete the quest the way I would like to.
