Summary0013354: FPS death during siege on a new CPU (Ryzen 7 9800X3D)
DescriptionI was attacked by goblins. At the beginning, the FPS were stable. I built a couple of walls.

Then, suddenly, FPS dropped to 5 making the game unplayable, as even the UI is laggy.

Exterminating ogres and trolls doesn't help. Exterminating goblins helps. I'm assuming pathfinding issues.
It's laggy even if I open the gate for the goblins.
Steps To Reproduce1. Load the provided save.
2. Unpause the game.
3. You get FPS death.
Additional InformationI didn't have such issues before, except one time under different siege, but back then it unclogged itself after invaders destroyed trade depot (or other buildings/constructions).
