Hmmm weird, something must have went wrong by using a save file from the 0.3 version. Ususally, the quest can't be completed without reaching STR-Lvl. 1 first.
I will have an eye on that and check if the problem occurs to others as well. For now, the only solution I could think of, is to restart a freh save in 0.3.1 (current version).
