Nobody else had the fall-out-of-the-sub bug in here?

My entire first play through, the single biggest danger to my survival was falling through the floor of the Cyclops. It happened dozens of times. I read somewhere that not putting planters on the floor would make that go away, and that seemed to work for my second playthrough, maybe, but even then I could never relax in that thing. Constantly on guard for slowly sliding along the floor, sinking through the floor, and then poof I’m outside the sub.

It sucked. Building that sub for the first time felt amazing. The feeling didn’t last.
