Patch #1 had to be reverted temporarily while Larian works on a fix for the savegames issue. However, this has caused some users to experience that their platform insists on downloading the whole game all over again. Unfortunately the only solution at the moment is to uninstall and install from scratch. However your saves should remain unscathed in \Documents\Larian Studios\Baldur's Gate 3 (do back that folder up just in case, though!).
Yeah, GOG does that

Ah well, least I have a fast'ish connection - if the save doesn't work though I might just cry
