Do Reaper Leviathans really ignore terrain?
I've seen the things go right through the sea floor sometimes. There was one time where one did catch me while I was in my unmodified Seamoth. It eventually let go, and I hightailed it back to base. I'm sure it was going to give chase to finish me off, so I instinctively (yeah... gamer instincts) flew around pillars, ducked through tunnels, and moving evasively as possible to ensure my survival. Thankfully I didn't get caught... Yet I've seen at least one YouTuber (8-Bit Ryan's second Subnautica video) try to hide in a tunnel from one only to be snatched up and eaten by it..
