I could not reproduce this (EDIT with Fane; I could trying with an undead henchman, though).
Please email a save before this (or a Dropbox or Google drive link, etc) to supportdos2@larian.com, with a description (or link to this discussion). If available, and this is not reproducible, also include a save after this happened.
Each save is a folder in the '..\Documents\Larian Studios\Divinity Original Sin 2\PlayerProfiles\<ProfileName>\Savegames\Story' folder.
In Windows Explorer you can zip file(s) and folder(s) by right clicking on it/them and selecting 'Send To | Compressed (zipped) Folder'.
