Can't decide if I've run into a bug, or I'm being dense. I'm going through the abandoned assembly yard for the first time in this playthrough and got to a room with a couple of large commercial constructors and at least one small constructor. I initially came out of the wall from a section that had some poison gas and some tubes you could jump up - 2 had alien containers at the top, the last one lead you through to a grate overlooking this production line. To the right of that, there's a section with a red block on the wall that says something like needs salvaged mining charge (can't remember the exact wording). There's a door opposite that, and a much bigger door on the end wall. Both those doors say Access Denied on them. I've watched Spanj and a couple of other vids of people running it, and that bigger door opens for them. Am I missing a switch somewhere? Or is that a bug? The only switches I've found is one back where the poison gas was - tried that one both ways - and a console in the room before that which appears to open a giant loading hatch in the ceiling under a crane.
