I suspect you're probably safer to install the Anastasia morphs into the same runtime as Alyson2 is in, General Nutt...?

I have...

I have saved a CR2 of Anastasia, after applying the morphs to Alyson2... and looking at this in textedit, it is of course referencing the Alyson2_HR.obz geometry file.

I imagine there might be complications for various things, if Anastasia was in a different runtime. But I could well be wrong in thinking that... I guess Blackhearted is the best guy to advise there...
