Re: Elder Scrolls: Total War battle crash (Mac)
The geography file crash issue arises only if the game got unpacked - there is apparently a time stamp issue involved, hence the two files need removing from the default data folder after unpacking. The same files within mod folders are not affected by this.
The banner files usually have only the texture files modified, I wasn't sure if ESTW had custom banner models (the mesh files) as well. I am afraid this is the extent to which I am able to help.
