[Q]

Kwok I sent you the savegame by e-mail as the upload here didn't work.
Are you sure you already have the insruction not to break the treaty in your scrips?
I looked at the BM 1.05 Scrip_AI_Politic.txt (did you post somewhere the newer scrip versions?) and didn't find it. There are instructions to make treaties and not to to declare war, which seems to function, on AI team empires, but where is this instruction not to break treaties with AI empires?
