Note: Idun, Freja, and B'og had voice types assigned randomly, so previously they didn't have voices. I have released an update which edits the BessEss.esp to give them appropriate voices and generated voices for them. So download both the main file and the update file and have the update file overwrite both the main mod + voice pack. However, this is the SSE version of the esp that I edited, so LE users probably shouldn't use the update.   Another note: MNC has a patch for Bestial Ess
