It has come to my attention that some submods for KGCM may be causing issues with patch 4.1 if they are not up to date. If you find the mod is not functioning properly please uninstall 4.1 and 3.0. Then delete the kingdoms_grand_campaign_mod folder so that any left over files are deleted. Then reinstall version 3.0 and 4.1 and they will work as intended.
