Map generation using the alternative IRMG map generator.

Hello everyone. So, generating maps using templates is clear, but how do you generate a map with a random template (without choosing a template from the list)? I tried it, and Heroes of Might and Magic crashes.

To the left of the file path for the template, there is a button that switches the mode from selecting a file to selecting a folder. Choose a folder with templates of size "huge," for example, and proceed; nothing should crash.
