Ok; you said you didn't get an option currently, so I misread the 'even if I have' as hypothetical.
Please email your latest save, as well as your most recent save where you still had the schematic, if available (or a Dropbox or Google drive link, etc) to supportdos2@larian.com, with a description.
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'.
