I made a modified Lydia, back in 1.5 patch timeframe (may've been 1.6) and decided to use her for a new game to test out the UFO mod. Now, I'd previously used a modified Eola made about the same time as my Lydia, and my Eola mod worked OK...

So, I put my modified Lydia .esp file in, activated the .esp through the game menu, started playing. Get to where I should get my lydia, and the old lydia shows up. I'm using quite a few different mods in this game, the aforementioned UFO mod, also the Cerwiden mod, and a new (to me) font mod...

So, is my old Lydia .esp file no longer usable post-dawnguard (the file looks just fine in the 1.7 CK)? Or does Lydia get treated differently post-dawnguard?
