I just started the DLC and noticed immediately that the enemies aren't scaling towards Nightmare power scaling. They have regular grey dots (normal scaling) instead of the red skull {overwhelming} and it ruins the combat because I kill most enemies in two hits while taking very little damage. For some dumb reason, all of the bunny rabbits that roam around have the red skull - but everything else doesn't...
I just completed Siege Of Paris and it was working just fine. I've restarted my game many times and changed the settings around, but they make no difference at all.
What's the work around here?
