Crashes when entering a town.

Hi guys! I don't speak Russian, so please don't pay attention to my grammar.

I'm currently creating a mod for HoMM5, and I'm having some issues with crashes when entering the Necropolis.

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

If anyone wants 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).

usually crashes happen due to memory overload; if the city has been repainted and the textures are heavy without compression, there will be at least lags.

a mod that changes the background in the unit purchase menu also caused crashes for me, probably due to the large number of objects.

I had a mod that replaced the Necropolis with the Order of the Blade city – crashes for unknown reasons.

there are many reasons.

P.S. I can only help with advice; I don't have time to go through the mod
