From the book of [PPZ]Kamikaze Gerbil, chapter 3, verse 16:
You have a room somewhere that is blocked off. Either you removed access to it by deleting a room/hallway or items are blocking the way.
No, sabateurs and infiltrators can enter your power plant via portable holes. The easiest way to prevent this is just packing your power plant completely full of generators, leaving no open spaces. Just be sure you have enough generators to meet your power needs, and/or have space to make another plant if need be.
