Description
[3.1.1] Looping AI fleets stuck

Game Version
3.1.1

What version do you use?
Steam

What expansions do you have installed?


Do you have mods enabled?
No

Please explain your issue is in as much detail as possible.
Observe the following fleets of the Commonwealth of Man:

- In the Deres system, Strike Force Minotaur is oscillating between heading to the Zosma system, and entering the orbit of Keresia
- In the Sastram system, Transport Fleet 1 is trying to enter the Hyperlane to the Zosma system, but every time it’s about to, it changes orders to “Following Strike Force Sphinx”
- In the Pentarum system, Strike Force Sphinx is oscillating between moving to the Deres system, and moving to the Zosma system

The impression I get from this behaviour is that there’s a web of dependencies that are updating in a loop.

ie. Fleet 1’s orders change because of Fleet 3, which changes Fleet 2’s orders. Fleet 2’s orders cause Fleet 3’s orders to change, which again causes Fleet 2’s orders to change again. So they just end up stuck in a loop.

Steps to reproduce the issue.
- Load up the savegame, activate Observer mode
- View the systems / fleets described above to see the looping behaviour

I have noticed this behaviour a few more times so it doesn't seem isolated, although a couple of times it resolves when I save and reload the game... so it's hard to produce a replicating save.

hopefully they can figure it out from your save game

My impression would be that there should just be some general rule to detect these looping orders after 5 or so loops and just force them out of it by blocking new orders for 1-2 minutes.

That being said, I don't work on Stellaris so I don't know how feasible that solution would be.

Saw sth like this with a transport fleet. It started to move away from a starbase only to return in the next moment despite on several enemy planets being bombed by its fleetscand it just having to choose where to go first.

Sorry to be a pain and bump this, but I see this behaviour constantly in my games and it's really frustrating. The AI actually seems to be attempting to behave somewhat sensible in a military sense, but so often gets caught in loops. I think fixing this issue would have a big impact.
