I deleted all my old saves. After about a dozen playthroughs, I finally managed to complete the battle with Chaos. The question is, was it worth it to exploit a bug just to summon essentially useless troops? I dug up the Ash and built it in Mythgard. I went to Holyflame and nothing happened. For some reason, Melchior obeys me. Okay, fine, 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 more buggy map (the behavior of the blue faction, especially Alaric the Lich, the battle with the demons, the weirdness with magic, not getting the amulet, and other minor glitches). Hello to everyone, and good luck, but I'm getting tired of all this.
If that's the case, I'll play through the map on Veteran again. And I'll see where you found these bugs.
