Main branch autogame log (for goldkeep ruleset run) contained "Wanted to cancel treaty but was unable to." -message. I looked it in a bit more detail, and the reason the treaty cannot be cancelled is that the target is dead.

While attempt to cancel a treaty with a dead player is not an issue in itself, it indicate that AI is doing diplomacy calculations in general against dead players, which might have other more serious consequences.
