... hmm, will it help? I mean, the transformation doesn't happen instantly, and I'm setting the limit in the old city? And how long should the delay be? Thank you in advance.

didn't help.

I don't know, the first thing that caught my eye was the sleeps; maybe something else. 10 should be enough, I think. Did you put a sleep after the transformation? In general, it's better to try to check the castle's race (or affiliation) and only then limit the buildings. And you can also disable auto-enter (automatic hero entry into the city).
