Modding

In the game, maps (*.h5m) are unpacked. As an example, I'll give you one path: Maps\Multiplayer\A1L10\. This is the map (A1L10). To edit it in the editor, pack the Maps\Multiplayer\A1L10\ path into a ZIP file (maximum size), and then edit it in the editor.

I manually edited each mission in the campaign, changing the parameter from the previous number to 40.
But now there's another problem: on some maps, heroes simply don't want to enter the town. Even movement points aren't spent after "entering," and with repeated attempts, the hero still isn't in the town.
Does anyone know how to fix this?
