Just noticed a bit of an odd AI behaviour.
AI relationship to me is at 7.16, mine to them is 13.01 (they spammed envoys at me, I haven't responded in kind).
They AI keeps offering me the L1 pact, and then cancelling it as soon as I accept. If I don't cancel my end, the AI will just thrash the pact back and forth, periodically agreeing to it again and then immediately cancelling.
Either the offerring and cancelling logic have gotten out of sync (shouldn't one just be the negation of the other?) or the AI is just playing a childish game of "Want it? Can't have it!" with me.
