I'm still on it, was very busy these days, I just checked if the last giants update didn't break everything. About cows, I tried different things but finally only the "ratio" doesn't apply, probably a giants limitation in animals script. I left orchard on the side as you plan to have them as "olive" so I'd like to see how many "trees" we can have on 1 Ha. Actually I was able to have 35 orchards on a 1 Ha field but what will it be in vine ?
Did you find a solution for the map color without using all the mod default-types ? I imagine that using just a part of the script could work .
