World Builder and Unity 5.2.2?

Is there a way to get World Builder to work in the latest version of Unity? Does anyone know what version of Unity broke compatibility?

World Builder imports fine, but I cannot access it via the window pulldown tab where it is supposed to be.

This is World Builder: https://www.assetstore.unity3d.com/en/#!/content/11333

 

Unless you fix it yourself , probably not, the last update of the asset was (Sep 25, 2013) build for 4.2.1.
You can try to contact the developer but since it its a free asset it's unlikely that he will fix it.
If the Asset is broken and is not showing up, you should check the console for errors.

 

That is the issue, there are no console errors. Because of that, there is no way of telling what is going wrong. Is there another way to check for bugs in Unity?
