The game crashes without displaying any error message, and it happens at the same time each time.

Could it be that a fan-made map adds a hero? It's strange that it didn't happen under the same conditions before, and now it does... If it's not a map with a hero or heroes from a mod that shouldn't be there according to the rules, then I don't know.

No, I checked even using the console command to scan the entire map; there are no special heroes, everything is as in the vanilla version of the game. I also have no idea... So far, I've only found someone in the mod group who has the same problem, but there's no solution, which is a shame.

What mods are you using?

Specifically, in the EWA (Elysium mods) launcher, I enabled the following features:

In the mod itself: I disabled creature spawning (I didn't enable anything else).

In the graphics settings: only the classic mouse cursor, the contrasting turn indicator, and improved environment models were enabled (I tried without them - it still crashes...).

In the launch parameters: patch for the map editor, autopatcher for new maps.

There are no other modifications; I haven't installed anything on top of that.
