OK, so the culprit appears to be appropriately named WTF. This mod raises the levels of the various encounter zones, dungeons, etc by a random amount. It can go as high as +60 levels. This makes it challenging when you enter an area at level 10, and it has raised the levels by 10. It's bat shit insane when you go into an area at level 2, and it is +50 levels. I just un-selected the mod, and re-ran Bash, ASIS, and DSR. I may play around with the .xml file to configure WTF to more reasonable levels when I get time, as a little challenge is nice, but I don't like spending 4 hours of realtime to get through BFB, having to save before every fight.
