Alright, so. I got my colony up and running. Sindrian Diktat and Persean League don't like that I'm stealing market share, so I constantly get disruption fleets headed to my colony. Ignore them after a while due to defenses being able to handle them, then head back to my colony to pick up a Paragon-Class capital ship, and, I kid you not, there are a dozen full size disruption fleets in system just orbiting around the colony from Sindrian Diktat and Persean League. Also there's a Tri-Tachyon but they're late to the party. My colony is completely inaccessible as it's just surrounded by a mass of hostile fleets with two-three capital ships per. I can't handle them all, and neither can the colony defenses.
Are the fleets supposed to stack, or shouldn't they go home after a successful or failed disruption raid?
