I've been getting this since BEFORE 1.3
Note: All my games are MP with 1 human ally.
AI constantly tells me BS about colonising nearby them.
From our perspective, it always looks like the AI is literally just talking to the wrong person.
So, my ally is bordered up against AI, but the AI almost always threatens me.
Then AI sends fleets to the right place - surround my ally's planets with fleets - but declares on me when I'm on other side of world.
AI is clearly cross-eyed, or has an extra chromosome.
Looks like an out of order/ incorrectly indexed collection.
Still good though. Fuzzy logic?
