I just started my first FS Campaign. My homeworld was between two MK IV teleport turtle worlds. At first I assumed this was part of the setup, but when the third shard spawned and was instantly captured on my homeworld, my suspicions flowered. According to the walkthrough, shards cannot spawn along a path that goes past MK IV worlds. I could potentially have recovered them all without an ounce of effort. Of course, I can never get off my homeworld!
