Crashes when entering a town.

Hi guys! I don't speak Russian, so please excuse my grammar.

I'm currently creating a mod for Heroes of Might and Magic V, and I'm having some issues with the game crashing when entering a Necropolis town.

I can't find the cause of the crash, so I would like to ask for help.

If anyone is willing to help me find the problem, why my game crashes because of the mod, I would be very grateful! (I will send the mod to anyone who is willing to help me).
