It's not a bug. Unlike other commanders, immortals won't retreat when all their troops are killed, or once a leader is killed and they're part of a 'leaders only' army. They may still retreat when the battle Lasts long enough to reach the 'autorout' phase - a feature that's been implemented to prevent unending battles.

You've assumed that the leader(s) I've seen retreat did so due to the 50/75 turn limit, and that I'm calling that a bug. Not so. I know about that rule (not that I agree with it, but that's been hashed out in many other threads as you know). I've never had any of my battles, in any game, Last more than 35 turns. I assumed that what I was seeing (the retreat) was either normal behavior (having forgotten about the tip text), or something else was going on that I wasn't aware of. This was 5-6 months ago when I was much less experienced, and trying out various nations and pretenders, and also when I wasn't in the habit of saving ALL my turns as I do now.

I think it has something to do with when the game computes dominion increase/decrease in the province, relative to when the battle takes place in the turn sequence. I've reported other problems in the past regarding when in the turn certain calculations are made.

I've seen a related thing happen when trying to exterminate an AI via dominion push. I see no enemy candles anywhere, I hold the enemy capital, and still the enemy god isn't permanently poofed.
