Well, I have finished my game in 1.0.0 now and wanted to revert my GOG copy back to current release. After choosing the right channel, GOG Galaxy retrieves the file list, begins - for a second - to download the 88 MB update. And then fails. Each time. Tried restarting GOG Galaxy, retrying by going back and forth between the channels. No luck. Is this a known issue? Any ideas how to fix it?
