ive just lost like 20h of gameplay because i reinstalled game and saves wont sync from cloud. When it will be fixed?
I've not seen any general announcement about this, so if you are looking for a response from Larian, I'd suggest reporting directly to them. There's a "report a bug" link you can use on the Larian launcher to take you to the relevant bit of their website.
That said, I'm surprised your local saves were deleted on reinstall. I'd expect them to be retained.
