OK, so I've been noticing a few trends in this......feature..... I apologize that I have no saves, only anecdotal testimony

, but these are things that I have noticed over the course of several different games. [An extra apology for how confusing this has to be to read, especially observation #2. If you can't make heads or tails of it, let me know, and I'll Worldbuilder some diagrams for you.]
On to the trends!
1. Small Archipelago, Cylindrical World Wrap: If I move my ships a few tiles EAST or WEST of my explored area, then automate them, there is a good chance that they will bee-line for the other side of the globe, just like I want them to. If I move them just to the NORTH or SOUTH, they seem to get stuck almost every time. (Hehe, like my use of vague language?)
2. Auto-explore units
seem to like distant unknows better than close ones. For instance, Let's say you have a peninsula jutting out northward from an island. Every time I have had a water unit on either side of the peninsula, and told each to auto-explore, the one on the left would go right and visa-versa.
Additionally, if a unit is moving back and forth, alternately facing a single unknown tile and the rest of the unexplored map, revealing the single tile seemed to clear up the confusion. Could it be that the units start too close to a square for the AI to prioritize it, move away towards something else, then (once they have gone a few squares) the AI re-prioritizes the initial, ignored tile, and moves back, causing a loop?
Has anyone else noticed the same things?
