I found a certain system with a blood red warning beacon. I understand that may be due to this mod (v1.2).
I appreciate a good challenge, but that one may be a little excessive. The number of patrols make maneuvering or sneaking away in the system very difficult, but more importantly because they respawn instantly you can get locked in endless battle if you're close enough to the source but not engaging it directly. Defeat a fleet (an armada, at that) and the next group will engage on the very next frame, with not a single moment in normal space. Retreat is not viable until you're under the disengage threshold, in which case you're probably doomed anyway. A slightly reduced number of patrols with a respawn cooldown would be significantly more manageable.
On the other hand, because of the endless battle the plunder from the system is absurd. I use it as a pit stop to stock up on fuel, supplies, and
other valuables. I'll get to the boss one of these days.
