I guess it could be a case of: treat it with respect, and it will likely reciprocate...

I just got this trying to claim Terroir. I simply reloaded the page and then the Add to Library button worked fine.

Reloading the page did not help for me. Always asking for credentials. I think the game was added but the library page couldn't show Terroir even after reloading it. Using https://www.gog.com/giveaway/claim did the refresh somehow.

I agree with this. It has very limited amount of questions and has been nothing short of annoying. Opening a ticket is a chore.

Thanks, I will try it next time when if I needed to contact support.

and here I was thinking " hey... a new forum game?? "

On seeing this thread title this morning, I was thinking this would be yet another thread about the chronic ongoing bot invasion that has been assaulting the forums for the past several months.

Sooo.... tickets.... for a movie or a sports event or a concert ?
It's the kind of analog timer counting: ticket 0, ticket 0, ticket 0, ticket 0.
Programmed to trash ticket 0.
