Epic War Age (EWA) - Adapted Mod Collection

I installed the add-on, and when the enhanced AI (Eternal) is enabled, the game crashes with a small probability when attacking mobs. As an example, I'm attaching a save file where the hero is right next to a mob. If I disable the Eternal AI in the launcher, the game doesn't crash. This save file is an example; it happened on 3 different maps. The game was a fresh install at the time, version 3.1. P.S. Could you please provide version 2.5 (the previous version)? I'll test it there.
