Remove the ability for blobs to spawn offstation

[ferriswheel1]

The main issue with blobs spawning off-station seems to be that they can expand unopposed, as no-one is likely to investigate deep space for em. But what if, when a blob spawned off-station, the crew received its location in the usual "aggressive macroorganism detected" announcement?

Blob fighting out in space sounds like fun, and announcing the blob`s location would make non-station spawning more of a trade-off rather than strictly better.
