Ah I understand now. I saw the message, it says about incompatibilities between the campaign and the mod. Here is a brief overview of the whole text.

Mod functionality that does not work in campaign:
- 8 skills option does not work
- Dwelling conversion may not work properly (it is not advised to use it)
- Governor setting is not advised as well

AI considerations:
- "Hammers of Fate" second campaign mission (Wulfstain campaign) cannot be completed due to AI issues. It is advised to use the MMH55_Utilitiy_64.exe which uses the original ToTe AI.

Game difficulty considerations:
- It is advised to play on normal or hard difficulty. The mod makes campaign easier due to balancing hero specializations.

Let me know if there is any area you dont understand with google translate. I will rewrite it in more simpler manner .
