well I haven't played the latest version yet (I didn't even k ow there was a latest version).
I've been playing in v0.1.03.0 for like the past 4 months so I can only speak for that version but I think the reason you can't get more scenes with those monsters, ie the goblin, centaur or wereslut, is because they're not major characters.
Maybe you can try getting farther into the map and you'll encounter more monsters to fight and therefore more scenes.
