I'd been playing using rtw.exe for a while before I switched to bi.exe. Well now I want to switch back again, the naval invasions just become an extension of stupid AI behaviour when you share a land border.

Do I need to do a clean uninstall-reinstall, or can I just change the TrivialScript back to running rtw.exe (along with changing some folder names back and deleting the map.rwm)? Will my saved game continue to work back in the other direction?

Or am I better off just doing it clean and avoiding any errors?
