Error converting from 1.1 to 1.2

Edit: Problem fixed (see post #3). Turns out not to be a 1.2/1.1 issue (see post #2).


I've been trying to get my mod (which works fine with 1.1) to work with the 1.2 patch. Unfortunately I've run into a couple of problems.

Firstly, I want to make use of the -mod:my_mod command line switch, so I put all the files for my mod that go in the data folder in an appopriately named folder in the Rome - Total War folder. I also put the world folder in there as well.

However this resulted in two problems:
1. A CTD when trying to start a campaign. (And yes, at all stages during trying to get the campaign to work, I have tried deleting the .rwm file)
2. When trying to start a custom battle, the game simply stays at the menu screen it's currently on, and doesn't start to load. No error message is shown upon exit.

If I copy all the data files into the data folder rather than the my_mod folder, then I can run custom battles with no problems. So I'm at a bit of a loss to work out what's wrong there.

I was able to get rid of the CTD when trying to start a campaign using the -mod:my_mod switch. Rather than simply having the folder world\maps\campaign\mod_name\, I added the folder world\maps\base\ and copied the relevant world files from my mod into that folder (I left them in the campaign\mod_name\ folder to be on the safe side).

However now rather than getting a CTD as soon as I try to load a campaign, I now get another, very strange error. And this error also shows up if I try to copy my world files into the data directory and run it normally (as you would in 1.1). The game gets maybe 5% into loading when it comes up with the following error message:

"Scene data chunk not found - See Tools Department"

with Abort/Ignore/Retry buttons below, clicking any of which results in a CTD.

Needless to say, I'm a bit miffed. Even using the exact same files* and setup as I have in 1.1 gets this error, and both copies of Rome (1.1 and 1.2) that I'm using for testing are clean installs.

Anyone able to help?

*Apart from adding the extra chariot attirbute in the descr_mount.txt file that the 1.2 patch requires.

Okay well now I'm getting this error with 1.1, so I guess it's nothing to do with the 1.2 patch. But for the life of me I cannot locate the source of the problem. Anyone have any ideas what might be causing a "Scene data chunk not found - See Tools Department" error during campaign map load?

Well I managed to fix the problem

In order to minimise the number of original rome files that I'm overwriting for the mod, I had changed the texture file references in the wonder and symbol_ CAS files in the models_strat folder. To do that, I'd simply opened up the CAS files in notepad and changed the reference towards the end of the file. Apparently the game doesn't like that. Oh well, everything's fine again, so I'm happy.
