Ok, then please explain why my first and only dupe death was caused exactly by the dupe building herself into a insulated block.. I was considering reporting _that_ as a bug, but I'm fine with having it as an occational building hazard... Unfortunately the bed time bell rang just when it happened so no one could free her in time.
I have the same problem. It only started after deconstructing my first coal generator and moving it to another room. It's completely ignored regardless of priority setting even though there's a coal storage next to it, the only way get them to refill it is to destroy one of the electrical wires connecting it and rebuild the wire again, then they fill it up immediately.
