Every time the AI tries to use a tunnel with a unit stopped at the target end, the screen gets covered with error messages, including one asking the user to report the problem to the forums. This is a pretty bad problem for my campaign, and I'm getting bug reports about it, so I'm moving the severity up.

Hexes reachable through tunnels are all highlighted as expected, but in the current implementation, a unit can't actually use the tunnel in some cases. In the attached image and scenario file, there is a bidirectional tunnel connecting the craters. You can select the saurian, then click on the swamp. It moves through the tunnel and reaches the swamp as expected. But, if you select the scout and click on the forest, it doesn't work. The scout moves to the first crater, then an error message pops up saying the tunnel is being blocked (by the mage)--though we know it's still open in the other direction. Even worse, this move can't be undone! That's a nasty, un-fixable surprise for the player. Also, if a micro_ai tries to send the scout through this tunnel, it will spray lua errors across the screen. For more fun, try planning mode.

The simplest way to fix this is to mark hexes at the other side of the tunnel as unreachable if a unit is there, but that doesn't make sense. Units on the same side can move through each other in all other cases, so they should definitely be able to do so in this case as well. For some uses, it might be desirable to have units be able to block a tunnel (in one or both directions), but that would still be possible with a few moveto events.
