rgnrk: Yes, I lost my last freebie too.
And yes, it says that the
message might take a few hours to be delivered. Mainly because it's not up to them how the email works, and if it works. But that doesn't mean that it shouldn't be in the "learn more" popup. And mine is not.
Basically, my hypothesis right now is 50%/50% between a bug with giving you the free game, or a bug with taking the counter down when they get out of freebies.
Actually, this possible multi-hour delay is pretty much par for the course for GOG. Most of the time when they have freebies, they say there may be a multi-hour delay, but the codes do get delivered eventually.
They don't try to constantly flush the queue, or whatever method they use, because their servers might blow up. They figured this out a few years(?) back with whichever freebie it was that nearly brought the site down.
