Summary:

The banner_icons.xml files from disabled mods are still read by the BannerManager. It'll cause:
- Empty slots are shown in the Banner Editor
- Custom colors from those XMLs are shown in the color list and can be applied
- If players select custom colors from a disabled mod and save that game, reading this saved game will crash the game because of invalid color IDs during the reading process.

Crash report ID:

2023-02-26_11.44.59_73509f88d40a0b79b5e7197ac89b8d6a

How to Reproduce:

1. Create a module containing the file "banner_icons.xml" in ModuleData directory
2. Define some custom banner colors
3. Start the game without loading this mod
4. In Banner Editor, the custom colors will show
5. Select a custom color and save the banner
6. Save the game
7. Load the saved game and it'll crash

Forwarded to the QA team for further investigation. We will reach out again if we need more information. Thanks for reporting and sorry for any inconvenience!
 
I can confirm this is not only true, but it's because even if you remove the module entirely the colors still load. If you create an XML file with colors and then change it, you will load lots of different colors. Also if you have multiple mods with conflicting colors so you streamline it, it gets messy.
 
I found another issue regarding the Banner color management. The method BannerManager.GetColorId seems not correctly implemented. It tries to traverse the BannerManager.ColorPalette dictionary with index from 0 to Count-1, but the dictionary's indices are not necessarily continuous.

When a mod uses custom color IDs not starting from 193, it'll crash the game when loading a saved game or creating a kingdom. I have to rewrite this method with Harmony as a workaround.

I had to accommodate this in my succession mod as I wanted a specific subset of colors but they weren't being found despite being in the banner creator because I used IDs I knew weren't in other mods but then weren't continuous.
