Xan has no face

I have several mods installed and for some reason Xan's face is replaced by a silhouette with a question mark. But in the character stats screen there's still his normal portrait. What can I do? I am playing BG:EE.
The mods I have are Xan friendship, chatty Imoen, NPC banter, unfinished business, SCS, portraits everywhere, Neera banters, quests and encounters, Coran friendship, journal fix, NPC tweaks.

Thanks for your help
