PAT0 problem

[JuncK2957]

Description of Bug:
When I change an animation texture list, no matter what texture the bottom frame index in an animation texture section is set to, when I tell the program to save the ARC file, it always automatically sets the the bottom frame index texture to the texture on the top of the list of the textures in the "PAT0 Texture Entry" settings section, then saves, and I only see it the next time I open the file.

To Reproduce
Steps to reproduce the behavior:

1. Change the list in, say, "D:\stuff\Wii Modding\New Super Mario Bros. Wii\NSMBWMV\DATA\files\MovieDemo\KDB.arc\g3d\model.brres\AnmTexPat(NW4R)\000_030KDB0\mat_player_eye\Texture0" for instance
2. Click on "File: Save"
3. Close the ARC file
4. Go to "File: Open..."
5. Click on "D:\stuff\Wii Modding\New Super Mario Bros. Wii\NSMBWMV\DATA\files\MovieDemo\KDB.arc"
6. Scroll down to "KDB.arc\g3d\model.brres\AnmTexPat(NW4R)\000_030KDB0\mat_player_eye\Texture0"
7. See error

Expected Behavior:
I want the bottom frame index texture in an animation texture section to remain the same when I save the ARC file.
