Elbe Valley 4x

[JaVaDy]

It's a wonderful map, but I noticed a "glitch": when one uses a cow pen, other than the cow pen that comes with the map, the cows you place in the pen won't be visable. I did read a message about the same problem occuring in a map called Stone Valley.

Is there a way to solve it for PC users with knowledge of XML manipulation and some knowledge of LUA ?
