I've been editing the descr_sm_settlements file for the Successors TW, so settlement models fit with the new cultures, but here's what I got when I launched the campaign :





Settlements that are now based on the greek/roman model (and that were previously of the barbarian culture) still has the barbarian 'ground' (I don't know which word to use for the thing I circled with red).
The same thing happens for all cultures and settlements.

Is there anyway to fix that without editing a TGA.DDS or a .cas file ?
