This small addon adds 2 stone forts to any M2TW mod. me_fort_a for Middle Eastern cultures and knightly_order_fort_b for all the others. (except mesoamerican)
The forts are stone on both the campaign map and the battlemap, do not need pre-placing and are buildable by family members.
Also makes stone forts on custom battle.
Unfortunately this does not work for Kingdoms.
Simply copy the models_strat and settlements folders into the data folder or your Medieval 2 mod, overwriting any existing files as you go.
For those of you that maybe interested or don't have a mod, this will work in the Wardog test folder.
