Fallen Knight

I deleted all my old saves. After about twenty playthroughs, I finally managed to complete the battle with Chaos. The question is, was it worth exploiting a bug to summon essentially useless troops? I dug up an Ash and built it in Mythgard. I went to Holy Flame and nothing happened. Melchior somehow submits to me. Oh well, I kill him, but I can't enter the city (even though it was mine before), so I don't get the amulet and can't go through the portal. The game ends there. I haven't encountered a buggier map (the behavior of the blue faction, especially Alaric the Lich, the battle with demons, the weirdness with spellcasting, not getting the amulet, and other minor glitches). Hello and good luck to everyone, but I'm getting tired of all this.
