Epic War Age (EWA) - Adapted Mod Collection

After installing patch 2.1, an error occurs when launching the game: Error: Subscript used on non-accessible variable
And the game stops launching altogether. What should I do? Should I manually remove all the changes affected by patch 2.1?

From the patch description: The launcher will scan for new maps when the game is launched.
This means that something is not working correctly with this scan, and it should have been simply disabled.

Thank you for reporting the error. It occurred due to one of the third-party maps that does not have a map.xdb file.
But the crash itself is my mistake; I didn't add a check for the existence of the file.

Patch 2.1.1:
• Fixed the "Error: Subscript used on non-accessible variable" error and subsequent application termination when attempting to process some of the third-party maps.
