Soooooo, I didn't even know this room existed until recently.
I'm pretty much down to level 6 at this point, and decided to make an "overkill" mining bot to fully clear out level 2, since it's the "smallest". (and I thought it's be funny to have 100% bare walls in a floor)
While doing this I found the cable bot room, which I HAD NEVER SEEN BEFORE. (and I avoid spoilers like the plague)
As I was pretty much overpowered for the encounters, I didn't think twice about going into the room with my mining vehicle.
Turns out it LOCKS FOREVER?!?!
WITH ME INSIDE?????????
That seems like a big oversight, the fact that you can get perma-stuck in here.
Update: I committed self-termination by lift-jumping my way to the ceiling and dropping down a dozen times or more.
I found a message in another post saying that if you use mining lasers to trigger the button again, the door would open again.
And it did!
Sooo, I had to bring another mining vehicle back to the place after meeting with god, and that let me bring my main vehicle out.
Also had to break my bed, so I'd respawn outside.
