0000176: Pathfinding not working properly with grates and ramps
I channeled out an area and covered it with grates with the intention of making a well system. After covering the ramps reachable by solid ground with grates, I issued the order to my miners to remove some of the ramps in the channel in order to be able to add Wall Grates. However, none of the miners would take the job, even though an acceptable path was available going over some of the grates to another ramp in the channel.
Removing one of the grates next to the ground floor that was covering an already-existing ramp let the miners find a path to get down into the channel area.

This may be an issue in regards to building things such as Walls, as well, though I didn't have a problem setting up wells reachable only over grates.

This could be lumped in with 0000018.

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.
