Yeah I can;t help feeling it's like this.
Which makes searching for them difficult, almost like patience is the thing.
Not that I'm advocating not searching for them but y'know.
I love the idea of roaming around on isolated planets, and I might roll over the brow of a hill and find..... SOMETHING.
It's pretty pointless though; even if we knew it's in the bubble, that's still probably several thousand planets on which we can land, each of which needs then to be searched. Best to just wander around and enjoy ourselves, chances are if there's anything to be found, it'll be found by someone not actively searching for (or even aware of) the barnacles or any other such mystery.
