While FRD is mostly working now I think, it does seem to stutter a bit, check out this save
Just watch the homeworld.
My fighter 1's from Soly are returning to Pepunu (homeworld), so watch the Soly wormhole closely.
You will see that my 100'ish fighters arrive on the scene, but that they decide in fits and spurts to engage in FRD behavior. Most of them will sit there and not chase anything in the system, then they will reluctantly break off in 1's and 2's and sometimes in larger groups to go chase. Eventually they all run to help, but it takes them a while to think about it apparently O_Oa
