How do you all do it??
Whatever I am doing it messes everything up. I usually wind up building on a aquifer scary level (non-undead) I usually wind up stuck above an aquifer (it does not matter if I encounter an aquifer, I still encounter the same pathfidnig bugs) and am forced to dig out a couple of non-stone levels before engineering a drop since freezing does not seem viable anyomre to pass the aquifers - but even before all of the aquifers, all pathfinding is destroyed.  _ before this I usually have a 3 wide ramped path going down 3 - 5 levels before expanding into rooms and long hallways and the stupid dwarves can not find anything even when messing with all types of warrens and none -

huh. i've heard about the deadly pathfinding alot but still have yet to encounter any problems. have you tried just saving and reloading, that's fixed it in most cases i've read about.

I believe there is something which [l]ocking a door, esc, and then un[l]locking it.  I haven't had any serious problems, but whenever a dwarf isn't doing what they are supposed to for no reason, this gets them going.

I have issues sometimes when I've just built a door or a wall or a workshop.

Restarting has never not worked for me though.

Just toggling lock on and off once always solves all non-legit pathfinding problems for me, regardless of the door's location. I've read that it supposedly forces the game to recalculate pathfinding.

Locking doors is a brute force method. Toady says that it would murderise the game's framerate (paraphrasing).

Guess what! Fixed in the new version! http://www.bay12games.com/dwarves/mantisbt/changelog_page.php?version_id=4

You don't lock the door and leave it locked, you lock it and then unlock it, and it causes a pathfinding paths reconstruction or the like. What new version? I just checked before coming to the forums, we're still on 0.31.02. *looks at bug tracker* Ah. You meant *next* version.

I deal with the pathfinding glitches by (a) not building ramps, and (b) destroying any ramps that are automatically created for me, and (c) if something glitches up because of some other reason (something being sealed off, for instance), I lock and unlock a door to reset the calculated paths.

Every time I've built ramps or made a channel which created them, they've just gone and completely screwed up the pathfinding repeatedly, despite my resetting it, until I got rid of them.
