You don't have any earlier saves, if you are not playing on Honour mode difficulty?
I don't recall anything like this being reported before.
Please email supportdos@larian.com, with a brief description and your latest save (or a Dropbox or Google drive link, etc), and one when Wolgraff was still in the party, if possible.
I'll get QA to check if there are cheat codes in the developer version that may be able to reset that. If the problem is something that would require a code change to fix, there is currently no ETA on when there may be another game update.
For Windows you can use the report.zip file generated by the
D:OS EE Analysis Tool.
Extract the zip file somewhere and run AnalysisTool.exe. When that loads, browse to the install folder (if it is not automatically detected), optionally run the tests first, and then generate a report (it will be saved in the same location as the Analysis Tool).
The report will contain system and game information, as well as your saved games. To reduce the file size, you can delete most of the saves from the zip (double click the zip file to open it in Windows Explorer, then browse down to the savegames_patch folder).
For OSX, saves can be zipped by right clicking the folder(s) and selecting Compress, in the folder:
~/Documents/Larian Studios/Divinity Original Sin Enhanced Edition/PlayerProfiles/<ProfileName>/Savegames_patch
Linux is similar, with the saves in the home directory.
