This is something I always seem to run into at different points in the game. The basic gist is, I will be on good terms with another Race ( sometimes very good terms ) and all of the sudden their Relationship Meter starts to drop a point per turn, and then they declare war. What irks me is that I don't feel like I'm doing anything particularly different from back when they liked me. It's not as though I've started raiding their Starbases or something.
I have some 'inklings' about what makes them mad. I don't think they like having my Military units inside their Influence. I don't think they like their Planets being inside my Influence. I also suspect that if I'm doing incredibly poorly Militarily, they tend to get unfriendly and then attack me, since I'm an easy target.
But what's weird is that I can be doing some of those things and they don't mind, and then one day they go apeshit. Is it just some meter that "overflows" and then your Relationship starts to drop? Do they start to care more at certain points in time? Is it just random?
If there are definite things that will always make them mad, does anybody know of a list? And additionally, is there anything I can do to make them happier?
Thanks much for the advice,
