@DraikenWeAreOkay, I took a look at the Familiars changes made by Tome & Blood and I'd recommend not to install WTP Familiars and the Tome & Blood Familiars components together as a general rule. They are truly not compatible.
About the specific issue you have been having with SOD, I don't know how to help you because I'm not a EE player and I only developed my modification for the classic engine and specifically for Baldur's Gate Trilogy. But I still have one question, just to make sure that the Faerie you were summoning as familiar in your game was the one from my modification. Does it have a portrait? Because if it doesn't, then you are not using the familiar from my mod at all.
