Welcome!
There are some mini mods put together for better AI. The most important files that it does change are the edb and edu files. They allow us to recruit the BG units if needed.
The easiest way to protect your earlier campaigns is to create another EB folder(either copy-paste or renaming your current EB folder to 'EB1' and installing EB all over again for WotB) and installing the WotB mod into the new EB folder.
