About human forts, I think they will be willing to target stuff outside their range (and thus move some) if they are put into FRD. Its just that they do not go into FRD even if the mobile military auto-FRD control option is on. You can still put them into FRD yourself. I'll need to test fortresses on FRD to be sure though.
Anyways, is it possible to push out 5.010 by tonight or at the latest evening tomorrow? This blade spawner bug is a MASSIVE gamebreaker for those unfortunate to get an AI that chose it. Again, I don't want to nag, but this bug was a decently big deal.
