Simple adventurer quest (woodsman axe, bear). I go there once, explore a bit then have to resupply. The adventurer is already on his feet, and I accidentally ask go through the quest dialog again. But that should be fine.
Anyway, I resupply and back in the area. Find the shelter, get the axe, go back to the village. But the adventurer now doesn't have the quest dialog anymore, also the usual ones.
In a fit of stupidity.. I "deliver" the axe to him, hoping it would make the quest complete. Doesn't work, though.
@Sami I'm sending you the savegame via email.. just after I delivered him the axe manually. Hopefully you can track down what went wrong.
