siege is broken: bug or feature?

[Slaists]

I've had it happen both ways actually. Sometimes they'll sally and when I win, I get the city. Sometimes they'll sally and I'll win, and the reduced forces return to the city and I face storming it along with a newly rejuvenated flintlock citizins group.

Sort of frustrating since it doesn't seem to be linked to how many of the enemy manage to escape my clutches. Sometimes a tiny number will manage to keep the city, sometimes a massive amount escapes and I still capture it.

yup. now that I think of it: I've had it both ways too. lately, I just autoresolve sieges (assaults actually) most of the time.
