As a player i don't think anything is happening, it's just coincidence, confirmation bias what ever.
But of course, every little sign gets us Beluaterrans on our toes.
As a player, I doubt it too. But they are really being a problem. When the invasion ended, a bunch of them appeared as these were the ones that hadn't been recruited during the invasion. They were killed. Then when Iato seceded, a whole bunch spawned again, but these were rather small hordes, so I figured they were leftovers as well.
These hordes are sometimes coming from the blight (mostly), but sometimes spawning in great numbers in our own lands as well. One 4000 CS horde has been coming back and forth between Drinilla/Tsamn and the blighted regions by Ete. Iato has faced a few large hordes, they came from the blight though I believe.
