Bug in the pathfinding
I was just innocently playing Blackwater Port when I was accosted by a rather insignificant-seeming bug. Moving Haldiel to 19,26 works fine, but 19,27 does not.
Attached are a screenshot of the problem, and a savefile.

It's all fun and games until someone loses a lawsuit. Oh, and by the way, sending me private messages won't work. :/ If you must contact me, there's an e-mail address listed on the website in my profile.
Is this with 0.8.9 or 0.8.8? Sounds awfully similar to http://savannah.nongnu.org/bugs/?func=d ... m_id=11196 which was fixed before 0.8.9 (and then made moot by redsun's new pathfinder code).

Of course, it is possible to tell based on the map...

I just like it when people submit reproducible savegame. Thanks a lot, I have fixed it.
For the records and those interested, an A* pathfinder is only guaranteed to find a good path when the distance function is an underestimation of the real travel time. Trying to outsmart the computer scientists that designed A* (by putting an 1.3 factor in the algorithm) is the fastest way to get a broken A* implementation. As EP savegame just shown us.
