Effect of the butterfly

What extension needs to be specified for a map so that it becomes a WoG map and starts working? I created a cool map for myself, but it doesn't work with commanders.

vidrakon, to do this, you need to:
1) install the WoG mod (the latest stable version is 3.58f);
2) install the localization pack;
3) in the WoG options, allow commanders (they are allowed by default).
After that, if you launch WoG, any map (even a "The Restoration of Erathia" version) will be played with the WoG features: commanders, creature experience, and so on. Additionally, you can (but it's not necessary) "WoGify" the map at the start: then some of the objects on it will be replaced with WoG objects.
Please, next time, ask your question in a topic that makes sense, and not just anywhere.
