0000104: No access to building material issue

Notes
(0000119) DoctorZuber (reporter) 2010-04-01 23:45	this is probably related to several other pathing threads. So far haven't gotten any clear answers on how to reproduce any pathing problems however. so keep looking.

I think it might be the game mixing up weather or not submerged tiles are accesible, (in this particular case) or subteranean and or special tiles (such as excavated aquifer tiles) are what experience this problem. After I wait for a bit with DF unpaused the problem seems to go away. Edit: Something I've noticed: When this occurs, it seems that a specific dwarf works on the construction. This is noticble when breaching aquifers because of the repeated job cancelations due to dangerous terrain. Perhaps the game is selecting a dwarf to build the item in question, and marks the material as unnaccesable if the dwarf is otherwise occupied. The other reason this occured to me is that the bug seems to occur after buildings have been placed for construction as well. I'll place a wall to be built, and no one with the appropriate professions will touch it, then after a particular dwarf wakes up, finishes eating/drinking/hauling items etc, he goes to build the wall.

Theory: it might have to do with places newly mined out, or places that have newly gotten access to via stairs/ramps... and perhaps they have not been "updated" with what materials/pathing can be done involving them. Likely same as 0000018 FIXES self after season change and/or save!
