Summary: The fleets spawned by the quest can be killed by other factions, causing the Horatio player to be unable to progress.

Description: In my last playthrough the fleets were generated in territory controlled by a Riftborn AI, by the time i got there the fleets were destroyed already, the quest did not point to the fleets' position anymore (even when pinned) and i was thus unable to complete it.

Steps to Reproduce: In the first chapter of the Horatio quest line choose Power, then let the fleets be killed by third party.

Reproducibility: 3/5 - The issue occurs when the fleets spawn in unwanted systems, you might need to manually move them with some developer tools in order to reproduce the bug consistently.

Expected Behavior: The fleets should remain in either Horatio territory or neutral territory (what if they close borders on me?), fleets shouldn't be able to attack/be attacked OR destroying the fleets should automatically reward the Horatio player regardless of who destroyed them.

Version: Latest version

Notes: The Horatio already have a vulnerable early game, having the fleets stay within Horatio's territory and having anyone kill the fleets complete the quest would be the ideal solution. 

Making the Horatio player hunt down those fleets far into the galaxy would cripple their weak early game even further (especially since the quest requires to build 5 ships with 100 defence, which you need to unlock with research, which cost more due to Horatio's perfectionism and you're going to lose some of those ships during the fight). 

The quest is already tougher compared to just having 12 Horatios (Grow instead of Power), it's even worse for a late game faction with a vulnerable early game.
