This is an incredible step forward, thank you!
When you have the time, would you mind listing off the mod set you're playing with? I've got a bit of spare time on my hands over the next few days so I might be able to isolate the Mod that's fixing the error. Once we find the particular mod, all we need to do is figure out WHY it fixes the error, and then use that information to create a sub-mod that functions purely as a band-aid for the fix.

Anyway, back to the real thing here. I've done two complete playthroughs (and I've started one just recently) with Prefixes for Enemies enabled in all of them and I haven't had any issues with the mod whatsoever. I'll be listing all of those three modlists juuust in case.
EDIT: from my current singleplayer playthrough, switched current to first
BIG UPDATE(?): I kept doing my tests after originally making this comment/post and I've managed to find out something. I did a large variety of tests very quickly and every single time I disabled Cheat Sheet from the modlist, I got the dreaded Kenneth Error. As long as I kept Cheat Sheet enabled at all times in the modlist, I did NOT get the Kenneth Error.
Which means, having Cheat Sheet fixes the Kenneth Error with Prefixes for Enemies? I would have never guessed.
