Questions about the Heroes 4 map editor.

Here I am! Of course, I'm a bit late, but the problem is really bothering me. It's the same as before. Now I finally have the opportunity to work in the editor, and again, the wolves just don't want to limit their growth!!! I've tried everything: I've set up a repeating event to banish one wolf if there are more than 10, and a calendar event with the same condition, and I've changed the number of wolves being banished, and I've tried everything else, changing the owners and the frequency, but nothing works!!! The only thing that worked was to remove creatures upon detection. Then it works reliably. But that's a standard event. And I have to account for a large range of possible wolf numbers - it's a time-consuming process. Is it really that everyone else has this problem solved???
