Anyone else seeing this? I noticed it as my shelf hit the 200 games mark.

Oddly, the 200th game pushed the bottom layer of the shelf to a new line even though there was room for it on what was the bottom shelf anyway, and ever since, when I first go to my shelf it says 199 games with the last game on the list (currently Teen Agent as I keep the free games at the bottom) missing. When I do a refresh of the page (F5 in the browser) the number changes to 200 as it should be and the last game is then visible, but on the new shelf row and not in the last slot on the penultimate shelf where it was before.

When my next GOG game is purchased I'll have to see if it starts missing 2 games until a refresh instead.

You might want to try the hard refresh - www.gog.com/account/refresh , I know for a while I was missing a few games, then they just reappeared. The GOG servers seem to suffer with the number of us here these days

Just done that now, but I'm not convinced it will make much difference as it wasn't as if any particular games were missing, just that on an initial load it shows only the first 199 in the list, and requiring a page refresh to show the 200th.
