Is there some unit or spell that has the ability to push an entire stack out of a city when attacking it? I've had a few cases in my latest game in which my opponents (AI, Calabim and Malakim) attacked my cities and conquered them, but left all (or almost all) of my defenders sitting next to the city. In most cases they probably wouldn't have been able to take the cities without the push (this makes it a little hard to defend effectively).
I also think I've seem a similar effect outside of cities when attacking a stack with a set of grouped assassins: they defeat one unit, then push all the rest away. But I haven't been able to make it happen reliably. And I'm not at all certain that this is what's happening to me in the other case.
Is this a known bug, or a super-powerful feature I'm unaware of? Or is this an as-yet-undiscovered bug that I should try harder to track down?
