Hey there, please send a savegame to support@larian.com and we'll take care of your problem.
After being so frustrated and losing my patience, i uninstalled the game and deleted my save file(sad and dumb. but true....).
Later, as a check, i got a save file from someone that was around that area and stil no key or abomination master.
I will send that savefile later today.
Thanks for your help.
