"Team" game - Humans vs AI

There's a problem with this setting. Yes it's meant to declare war on all humans all the time. But when I logged on as them, they were declaring war against everything and everyone. Furthermore, they were making treaties all the time too - I got a bunch of tech because they traded with me, then immediately went to war with me the next turn (enough for 2 tech transfers to happen).

Minor note: the AI tried to retrofit a cargo ship with items onboard while I was watching.
