On the main menu on the left hand side in the Cossacks 2 box under the title C11 Modding, sub title Modding editor, there are editors for Stones and trees. The stone editor starts;

This Editor allows you to manipulate about anything that can possibly be done with the various stones in the game ( small stone's, mine's,...) and there are pictures of the editor in use.

I wondered if it would work with AC and ACFD.
