For some reason the respec is also adding the deal to trade 2 attribute points for 2 reputation.
Please email supportdos@larian.com, with a save before respecing (or a Dropbox or Google drive link, etc), preferably the one with all equipment removed, if you saved then.
There is no timeline for another game update, though, so as a workaround you may be able to use CheatEngine to boost dexterity a couple points. You would need to be careful with the program install to avoid the extra 'offers', though (see
here). I don't know of any other trainers.
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 all but one of the saves from the zip (double click the zip file to open it in Windows Explorer, then browse down to the savegames and savegames_patch folders).
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.
