There are a number of games that a would like to add to my library that are currently 100% off. I'm able to download the install files properly, but the games don't show up in "my purchases", with the exception of Lieve Oma. I'm also seeing the "Buy for $0.00" option for games that should've been registered to my account (same issue, just showing it hasn't gone through).

Any help would be much appreciated

Thanks!

I made an issue for this a while back. It's been added but not released just yet last I knew. Just added a comment asking about the status.
