So normally getting the king to agree to a truce, convincing Edgar, handing in the quest to the king for the truce xp, killing him for his head to turn into Edgar and saying it didn't work out, gives 2 rounds of experience. However in my run today after going through these steps, getting the xp from the king, and then killing him for his head, I went to Edgar to hand in the head and there was no dialogue option for it. Not sure if the dialogue got bugged somehow but usually I can do this the same way each time and it works. Its even listed on the wiki as working before.
Can someone else try and confirm this?
