Epic War Age (EWA) - Adapted Mod Collection

The mission is progressing as follows: We capture the city, free Isabel, and a couple of days later, Agrael attacks the city, and we defend ourselves. Then, a week later, an Inferno hero arrives, attacks the city, and you have no chance of defending yourself. The hero has 50+ Ice Demons. And this is the 6th day of the third week of the first month.

I have the following problem: The game crashes when I try to play maps that have indices before the name: A1, A2, B1, B2, E1, E2 (these only apply to Multiplayer maps and single-player scenarios).

The mod was installed on the licensed version from "History of Two Worlds" and updated with the patcher to version 3.1 (downloaded from here: /files/10078/>)
