"Could not find path"
« on: October 20, 2009, 01:49:39 pm »

So, I was digging downwards looking for metals and such. After I dig down to a certain point I am flooded with hundreds of these messages and my game starts going unplayabley slow. My miners can't seem to figure out how to get out of there.

There is a direct, large, and unblocked path to the surface. Why can't they use it?

Maybe you hit an aquifer? Although you would be getting a different message if that were the case.

Turn announcements to show no job cancellations, that should fix the lag issue. Find one of the stuck dwarves, enlist them, and try to find the cutoff point.

I don't know what you mean by cutoff point, but enlisting and unenlisting seems to have fixed the problems.

Why would a military dwarf know how to go up stairs and a non-military dwarf not?

Also, is there anyway for me to dig fairly deep down without everyone getting stuck?

Edit: Nevermind, the problem was only fix for a few moments. Now almost all of my dwarves are getting the error, not just my miners. It is "cancels store items in bin/store item in stockpile: could not find path".

There is no path problem, I don't know what stockpile they are trying to use, but none of them are blocked off.

By cutoff point, I meant where they got stuck and were doing the could not find path spam.

By using military dwarves, I mean station them at various points on the pathway to find out where access got cut off.

Enlist a dwarf in the mines, and station him on the surface. Can he make the path? If not, then you've managed to break access somehow. One common way to do this is with ramps. You can't make U-turns with ramps, and they need to have a wall tile adjacent to them that the dwarves can stand on.

When in doubt, add some stairs.

You probably managed to mine out the one ramp (or up-stair) that was necessary for the path.  Easy to do.

Read wiki on "ramp" and "stair" to better understand their mechanics.

It shouldn't be flooding him with hundreds of messages, though. It should interrupt once.

What job is being canceled repeatedly because the path couldn't be found?

I remember a case where the bookkeeper was cut off from his office, and spammed the couldn't find path message repeatedly because he couldn't update the stockpiles.

Sounds like something similar happened, but the basic problem is the same. Dig some new access for your dwarves.
