I dunno if this is a bug, but...
Visited Ethexae early in the game. Unlocked her personal quest. Decided to do it later. Came back to Myrkkan I on turn 24 for Agonaglia. Passed the Endurance check, but not the Sprituality check. Talked to Ethexae, didn't get her approval. Went to Heru III on Turn 26. Talked to Radomil. Game says I lost the Starfall game.
But I never played the Starfall game, so that doesn't make much sense.
Thanks! Great game! Having a blast.
