Potential repro steps found, from the discussions:

I found a way to reproduce: This is happening when you're passing uninhabited spot with some monsters on your tail

1. travel from outpost to empty spot
2. teleport the sub around the level, make sure something spawned, but don't kill it
3. teleport to end, transit to some next location
4. take a look around, there's 100% something prespawned. Sometimes it's just a few crawlers right outside the sonar radius, sometimes it's 10 hammerheads on top of your sub

If you retry or save-load nothing will spawn It can happen when transitioning from outpost to outpost, but i don't know exact conditions for that
