Baffled by error that didn't exsist before

I had a beautiful working campaign. Buildings were great, settlements perfect. No errors with the descr_strat or region. Rebels and mercs all set up. I'd even played a bunch of games where I battled sieges and on regular battlefields. Everything was great. So I then make a change to the descr_walls.txt, I give the carthaginian culture roman walls and edit the texture so they are still the sandstone color. The campaign loaded fine, however when I tried to start a siege battle or view the 3d overview of the a city errors started popping up and causing a CTD. Before I made the changes to the descr_walls.txt everything was fine, as I already mentioned.

So I made the changes, mostly to do with triggers for traits, ancilliaries and advice. No problem, those needed to be done anyways. Those out of the way a new error popped up. It said in my descr_strat.txt that my government building had to be one below the settlement size. Which meant I had to change a few of the huge cities core buildings to the imperial palace. Again no biggy. So I try again and another error. THis time I'm told I can't have ANY buildings in a village, including core government buildings. Meanwhile before I edited the walls I had plenty of the buildings which I had set to require the village level and had no errors. Heck I even played sieges in the villages with no errors. But I can't not have buildings in the village, my mod requires that I have certain buildings present. So, I revert back to the original descr_walls.txt, delete the map.rwm and the same error loads up when I try to have a battle with a settlement of view a settlement in 3d.

Somehow this one change has completely screwed up the game and I can't seem to find anyway to fix it. Which is INCREDIBLY frustrating. Does anyone have any idea what I may have done to screw things up?

EDIT: Well I did some digging found a file wasn't in the right folder (a dds texture) and put it in the right folder. So now the thing loads a 3d map however when I exit the game it now gives the same error in of a village needing to have no buildings. Grrrrrrrr

It is possible the fault may have been masked before. The village building error is an exit error and non-fatal. Although you can set and build buildings that require but a village level, the game complains with the non-fatal exit error report if you assign buildings to villages in the descr_strat.txt file.

You can use a script to have the game place the buildings in the villages at game start though. Evidently everyone can get this to work except me :) so you should be able to do it: https://forums.totalwar.org/vb/showthread.php?t=63561
