1. Did you play on an older version? I think that's an old bug that was fixed by now. The events should still advance normally, it's just that in your questlog the quest isn't marked as finished.
2. They're in the top right corner on the map where you find the Demoness with Naevy. They're purple/pink pillars, two tiles tall.
3. You need to advance the main story, the political meetings with Begus, the paperwork on your desk and the events with Kurohime so that you had the events with the orc camp in your paperwork.
Ah, I thought because the quest hadn't gone through that it was creating with furthering the story. I've had the first meeting with Begus, but I haven't had the 2nd. How do I trigger the 2nd meeting, I went back to the church and talked to the guy and all he said was that he'd "inform me if any news came up on the criminals". I play one the most recent version. I've had the orc event and have reached the pinnacle of the story with Kurohime for the time being.
