Thanks for the hotfix! Any chance we might get the GOG offline installers before the weekend?

Galaxy works perfectly. I have no problems with it. You'll get the patches for all your Gog games faster using Galaxy. I only use offline to save my backup installable copy of each game, but I don't download the offline installer until the game has received its final patch--otherwise I'd be doing a lot of offline downloading for nothing...;) Not sure why people shy away from Galaxy these days--the new version seems very solid to me.
You seem to be very happy with GOG Galaxy and that's great. I just happen to prefer the offline installer instead. I am not sure what you mean about "offline downloading for nothing", though. When a new patch is released, there is usually also a single (offline) patch file available so the download size should be identical/similar to what's happening via GOG Galaxy. However, in the past, BG3 offline patches were published with a fairly big delay but this has now changed thanks to Jess.
