Problems editing retrofit mod

[Rhyfelwyr]

I know several M2TW files are incompatible with the retrofit mod due to it using the kingdoms.exe, but I thought the only incompatible files would be the ones you can see in the data files of the retrofit mod.

Files like EDU are obviously incompatible due the the recruitment_priority_offset issue, but I am getting crashes when trying to go to the Custom Battle screen having added new files into the retrofit folder.

These files were fine with M2TW, and I do not understand why the game will not work. Basically, I added into the retrofit data folder (in their appropriate locations):

DATA FOLDER:
descr_banners_new.xml
descr_character.txt
descr_lbc_db.txt
descr_model_strat.txt
descr_offmap_models.txt
descr_sm_factions.txt
I edited retrofits EDU rather than adding the old one

DATA/TEXT FOLDER:
campaign_descriptions (Text and BIN files)
Expanded (Text and BIN files)
Imperial_Campaign_Region_and_Settlement_Names (Text and BIN files)
Descr_names (Text and BIN files)

+ the fully replaced the Base and Imperial_Campaign folders

Does anyone know if my problem is due to files being incompatible with kingdoms.exe, or if this is a mod folder issue?

EDIT: I think this problem could be related to character names. Since I added some names when following the tutorial on adding factions, I think I may be onto something. Out of the 3 files I mean there are

descr_names.txt (in the data folder)
names.txt (in the data/text folder)
names.txt.strings (BIN file, in the data/text folder)

Now, I mucked up a little here. Basically, I put descr_names.txt along with names.txt.strings in the data/text folder, and didn't put any of these files in the data folder. In this situation, the campaign work (none of my new factions with new characters names were added yet), but I got crashes trying to load the Custom Battle screen.

Since I presumed only the names.txt.strings file was needed in the data/text folder, I moved descr_names.txt into the data folder. But this gave an unexpector error message loading the retrofit mod.

So I am wondering if this file is incompatible with kingdoms.exe for some reason. Would that explain crashes at the custom battle screen?
