Me too :(
Maybe we should contact support if it doesn't fix itself by a reasonable amount of time.

Same thing here. I don't think I'm actually missing a game; it's just some kind of display error. I'm sure it will get fixed.

Can't be sure either. Have no idea what should have been there, if anything. It might be a display error.

Tried looking at it in list mode?

Good idea. List mode shows no gap. My gap is in-between "Might and Magic 9" and "Mind Path to Thalamus", so I can't think what would be there anyway.

There's a list mode?!
Nothing was missing from the list mode. Anyway betweet LU and MA (Lure of the Temptress and Machinarium) it's very unlikely for something to exist. It's probably a display glitch.
Question: How is it possible for the list mode to be slower than the thumbnails mode?

Yup.

On list mode there are no gaps, but I THINK that if the game is missing, it is not displayed at all under this mode, therefore the lack of gap (or at least, I thought so when some similar issues happened during the Nordic Games sale).

It's okay here.
