What the Heck

[Teleklos Archelaou]

There is a weird bug with RTW that makes reinforcement armies from inside cities totally disappear (AI mostly) if the battle is fought out and reinforcements never arrive (usually do to the player's cpu, and whether or not the game thinks he can handle huge armies in large numbers - unlimited numbers), but the other army (the one outside the city) is defeated. Maybe it works the same way if it is a draw. But this is not fought out, but auto-resolved. I think it's possibly related to this issue, but I certainly don't think it's because of something we've done.

I was under the impression that armies being flipped out of existance only happens with rebels. Unless there is nowhere to retreat too, such as when on a tiny island. Which doesn't matter if your sitting in a town. When enemy reinforcements arrive from a town I make sure to whipe them out, because it saves me doing a seige the next turn.
