Howdy Belter,
That line that's going through the central spine on the Tier 1 Merchant ship means that the spine's no longer stable. Those modules are toast. remove them from the layout.
Good news is that you're EVA-certified and can Spacewalk with the best of them, right? Bad news is that more'n a few Belters have bit it going for a swim when they didn't mean to.
Chariot out.
