0000901: Cutting off access to outside areas causes lag and buggy pathfinding.
I'm using wall grates to cut off exterior access to keep all the goblins out. When I do this I get a whole variety of canceled task messages because my dwarves can't find a path. This would make sense if they needed to do anything outside but they don't. For instanced they'll constantly cancel drink even though there is clear access to my booze storage. Sometimes it will also make the game really laggy. Removing or opening the wall grates clears up both problems.
Just cut off access to the outside world. I've done this a few times already in different ways and something similar happens each time.

This and other issues are being marked resolved because they fit the symptoms of the general pathing bug described by issues 0000018 and 0000070. If this issue represents an additional bug, it will most likely present different symptoms in 31.03, and a new report should be submitted.
