There should be a cutscene there where Icara shows up and heals Zandalor.

Please email, with a description of the problem and a save before approaching Zandalor (if available; your latest if not).

For Windows you can use the file (or a Dropbox or Google drive link, etc) 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 all but one of the saves from the zip.

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

Linux is similar, with the saves in the home directory.
