The quest text is quite weird. Some of the unsolved quests don't actually feel like quests. It's just something that happens that has no apparent follow up, but it's still shown in the quest log? Okay.
This is one of the main core ideas of DOS for the quest systems. Originally, as far as i remember, there weren't planned actual "classic" quests, just journal entries. I assume due to Kickstater the idea shifted towards a bit more classic approach since apparently people want to see it again instead of trying something new. But game still follows the same concept - no apparent quests. It was mentioned few times in interview and KS updates.
