Summary0007412: Dwarves will cease using dug/constructed ramps after some time
Descriptionsingle and vertical/horizontal rows of up&down ramps properly aligned along the z-levels with proper walls in place for ramps to exist on are no longer pathed to or across with no discernable trigger. Reconstructing the ramps does not re-activated pathing.
Steps To Reproduceembark, dig an entrance using ramps, observe dorfs (and also wagons, so presumably all other creatures too) eventually becoming unable these ramps for no obvious reason.
Additional InformationHappens fairly reliably (so far ~ 70% of emarks have encountered this problem eventually, though usually before any migrants arrive) on different worlds.

Reminder sent to: Orkimedes

Please upload a save that demonstrates the ramp issue to the DFFD ( http://dffd.wimbli.com/ [^] ) and post a link to it here.

I noticed that it takes ~a few seconds for the bug to re-instate itself in a bugged save upon loading. The time it took seemed reasonably consistent though. I pulled the lever (connected to the drawbridge) a few times to make sure it wasn't blocking the access route rather than the ramps.

I have been playing the supplied save for a quite a while, and cannot reproduce the bug. The only times the depot is inaccessible are when the lever is pulled to raise the bridge, with the usual lever delay.
