I started a new game and just went through Bleak Falls Barrow. On the way back to Riverwood (the way past Alise's hut), I ran into a bear, some bear cubs, an ancient spriggan patriarch, and a winged twilight. I am level 6. I was not aware any of these mods would cause out-of-level encounters, but apparently that is not the case. Which mod could be the problem and how can I fix it? I best guess would be Immersive Creatures, but I don't know why the enemies are so high above my level.
