Mutant bandit in Fort Strand
(Summarized version of my post in the Bethesda forum)
Here is an encounter I had at Fort Strand (ruins directly East of Anvil).

My first thought is that something went bad with MMM and/or OOO, but I have learned enough about mod interaction to know better than just go with my first feelings about this kind of issues.
Also worth noticing - the VERY large number of bandits outside Fort Strand. I counted more than a dozen (usually, I only get 4 or 5 there).
After following some suggestions from the forum, it looks like the mutants were caused by a conflict between the new version of MMM, TNR All Races and an old version of Wrye Bash used to try and merge the levelled lists.
I downloaded the latest version of Wrye Bash, used it to update the faces of NPCs only (and leave levelled lists alone) and I haven't seen the mutants ever since.
