[40D11] Caravan Can't Find Road after Reclaim
« on: June 20, 2009, 12:43:44 pm »

Reference Picture.

On the left is the fully-enclosed road the caravan faithfully found every year prior to retaking the fortress.  It leads directly to the depot with no obstructions and no forbidden anythings, and the finder proclaims the depot as Accessible.

On the right is the caravan whose wagons have bypassed me for the second year in row now.

Is there any particular reason?  I'm going to rip out and rebuild the road and bridges but would like to know if that even has a chance of working.

Ripping up and rebuilding the road did not help.  No caravans can find the depot despite it being Accessible via the Finder.

Ie. it's not forbidden?

I've not only reclaimed it but ripped it up and rebuilt it.  The traders wouldn't path to a forbidden depot anyway.  Traders can, but for some reason their wagons cannot find the great stupid 4-wide red carpet leading to it.

It says 4-wide; have you considered making it five wide?

Give it a try. 's worth the attempt at least.

Why 5?  You only need 3, the "depot access" thing shows tiles that the wagon center can and cannot path on.

If you rebuilt it, then the components clearly can't be forbidden...Hmm, I have no idea then.  :/

When I lower the bridges, sometimes they spawn really really close to the road -- this time in particular, they spawned right next to the bridges -- but they never, ever, ever spawn on the road proper or on top of the bridges.  Not even elves do, they wait forever for the bridges to be lowered, but spawn right beside them if the bridges are down.

So they hate the location for some reason.  I've torn everything down and rebuilt it but they still hate it.  Maybe the game somehow thinks an area has been forbidden.  I'll see if scooting it over five squares helps at all.

The problem may not have anything to do with reclaiming.  Recently, on a new fortress in 40d12, the Dwarven wagons bypassed my "inaccessible depot", despite the fact that shift-D told me I was accessible.

I was, however, trying to force the caravan to follow a specific route, in order to avoid the problem of goblin ambushes far from my fortress.  I had a three-wide tunnel from my underground depot to the closest map edge, ramping up to the surface at the last minute.  In a previous game after doing just the above, I saw the caravan approach from the wrong direction and then "turn on a dime" to enter the tunnel, so I added a channel around the tunnel mouth.

From his picture, it looks like the OP was doing a similar thing with walls.  Could Toady have reprogrammed the caravans to be less tolerant of herding?

Again, shift-D told me my setup was kosher, but I got bypassed.  This remains a bug, since shift-D should never lie.  (Also, if there is a change, the Wiki should be updated, since it says herding works... (http://www.dwarffortresswiki.net/index.php/Caravan#Wagons))

Ah, but my herding worked in 40D11, having never been played in a different version.  Its only in reclaim, in the same version, did I start getting bypassed.  There were, previously, no bends whatsoever in the road, just a few (working) ramps.

At great expense of dwarven life I have moved the road over a few tiles.  The results so far are promising, with at least the elves having enough sense to spawn inside, which they never managed before during this reclaim.

I can only state that Ive experienced caravans spawning on any edge of the map despite having a road built to the edge, normally leading to the wagons getting left behind.

Success!  The wagons spawn right beside but not on the road.  For some reason it won't find areas that were a road previous to reclaim.

I know.  Which is why I don't use tilesets.
