I first noticed this in Bonehill in BG1, and thought it was mod-specific. But then I saw it again in a halfling merchant in the wilderness south of Candlekeep, as well as in a merchant in the Cloakwood Mines area. I then saw the problem when I moved to BG2, this time in Arlax (in the Region of Terror mod) with a few of the merchants in the streets and again in Riatavin (don't know which mod this is from...).
As I said, it's not a critical problem, but I just wanted to see if this was a known issue.
Attached is my Weidu log. It's the SMM Auto Installation (except for the Black Rose mod which I couldn't download) with some NPC mods.
Thank you.
