The current CA - Blood and Smoke version has a problem that could lead to crashes during the mid-game. This issue arises from "phantom soldiers" that are undefined, caused by naming differences between the files and the submodule.xml.

So, to fix this you can follow the steps below:
1. Go to your Bannerlord Modules file, then open CA_BloodSmoke and open the ModuleData
2. Go to cultures folder and rename everything into this format (cultures_xxxxxx) so from "aserai_culture" rename it into "cultures_aserai"
3. After, renaming everything then go to "EquipmentRosters_npc" and rename the file into "EquipmentRosters_npc_empire"
4. Then, go to the "EquipmentRosters_troops" and rename the file into "EquipmentRosters_troops_empire"
5. Then, go to the "items" and rename everything into this format (items_xxxxxx) so from "vlandia_items" rename it into "items_vlandia"
6. Then, go to the "partytemplates" and rename everything into this format (partytemplates_xxxxxx) so from "aserai_partytemplate" rename it into "partytemplates_aserai"
7. Finally, go to the "troops" and rename everything into this format (troops_xxxxxx) so from "empire_bandits" rename it into "troops_empire_bandits

By following these steps, the game will detect the files correctly, resolving the crashes.
