Summary0000800: Squad attack pathfinding lags behind target movement
DescriptionI had a Yeti get inside my fort and the yeti was able to elude my lone speardwarf (and his 3 war dogs) for weeks of game time because it uses the same type of pathfinding (caches x number of steps ahead of time) as other work jobs.

A dwarf will run at him and the yeti do a half circle around him and the dwarf will keep moving to where the yeti was 5-10 steps ago.

Dogs have better AI (since they don't use the kill order), but are too slow to catch the yeti (in fact slower than my dwarf).

At one point I felt the urge to play the "yakety sax" song.

Yeah military dwarves path to the place where enemy was when they started pathing. When they reach that place they start pathing to the place where enemy is at this moment. This caused situation where half of my military is chasing a groundhog for 2 months around the whole map.

Yep - I've had some pretty legendary elk bird pursuits through my fort.

elk birds..I wish. I have the "civilian flees into danger instead away from it, ignoring alert, runs outside, is chased by goblins, military on kill chases after goblins" and then they do circles on the map for months unless I study the movement pattern and manage to block them off with individual orders or a second squad. (note to self: next fort will be in a steep canyon/on cliff with lots of impassable features)

Toady has started asking for saves for military/equipment bugs, so if you have a save demonstrating this problem, it might be helpful to upload it to http://dffd.wimbli.com/. [^] Thanks!

It's more or less just an issue with the way military pathing works, I don't know that saves would really help illustrate this one, unless the military isn't supposed to path like Rafal99 described.

I noticed this too when my military was chasing a giant rat, later on when they were chasing a cave swallow. Took them forever to catch up.
