This is about the face patch file bIntegrationEV - Alternative NPC Faces by LazyMonk.esp

It wants three masters: bIntegrationEV, LAME, and RBP

I have bIntegrationIntegratedEV, which I understand has incorporated all three mods into one .esp file

So, I went into Wrye Bash and replaced all three masters of LazyMonk's .esp to bIntegrationIntegratedEV.esp

After I imported the NPC faces I loaded the game and it worked

My Question: Is it okay to have an .esp that wants three masters which are the same file? I could not find a way to remove masters with any of the Oblivion utility programs I have. I am only using LazyMonk's file to import faces, the .esp is not activated.

Depends, but should be ok in this case since the formID's are retained in the merged version of Integration. I remember having to fix something with Tes4edit though, you might want to check the .esp. I actually converted the Unique Clothes plugin as well, would be nice if there's an official version of these optional mods though.
