That is the bug I was looking for, but it always asks me for a DoW when I try to recreate the situation using the world builder. I could swear I've seen the bug you speak of, but I was starting to doubt myself before your last message. Since it's not going to ask if you want to declare war on the friendly units, I would argue that it should not show combat odds against those friendly units. I could understand changing the functionality for something like BULL, but for an UP fix, I think the original intentions should be honored. Keep the effects of dragging, right clicking, and holding ALT consistent, and just don't show combat odds against friendly units when attacking that plot won't ask you to declare war. I could probably find the cause of that bug if I could get a save showing the bug.
