Bleh. Removal of the ignore option on this is not a good thing at all. I got the request and went ahead and selected just passing through. Mongolia was on another continent and I certainly had little interest in them I just figured an auto explore scout was lingering around them a bit too long and that I would have to go and manually move it away. I always ignored in the past just incase an auto explore scout could set it off. I am too lazy to scout manually past the first couple dozen turns so all my scouts get switched to auto at some point. I was right and wrong. It was one of my scouts. One who managed to do this to himself. This thing should really be triggered by a strength comparison. If your units on the border are powerful enough to register as a threat to their army then they get antsy. A lone scout really shouldn't be causing diplo penalties. Well at least this was a laid back 1st game to get used to the new features. On this difficulty level it doesn't really matter if I make enemies with any given civilization, even with suboptimal play due to experimenting. Anyways the real point of this thread is what are the exact rules on this? How many tiles away, how many units, etc. It isn't uncommon for me to have garrisoned encampments or even cities 1 or 2 tiles away from a shared border. In the past I just ignored it rather than risk a penalty due to not spotting a place where I was breaking the rules. Now I apparently need an encyclopedic knowledge of what is or isn't too close. Be nice if the game came with a promise overlay that would tell you where the limits of any given promise was.
