Randalator: I can see all install and patch files on H:ZD, no zooming or other trickery needed. Firefox 95.0.2
Are you using any kind of ad or script blocker?
I use a bunch, i block everything but GoG and GoG-Statistics as everything else is junk and tracking.
Cheesy-Beaver: But I can't scroll down to click anything. I didn't think I'd have to change resolutions but even than it doesn't show files 10 - 19 to download.
Hmmm tired zooming out? Ctrl -, or Ctrl-MouseScrolldown.
I would assume there's a lot to see but there aren't that many items on your shelf, thus the scripted popup of the game isn't updating the length of the page? (
and if you click outside it, it goes away) As suggested you might reload the page and open up the game option again and see if it is fixed.
Alternatively if you have the link for the files you can post the later ones manually in your URL if you have to.
Rebel Galaxy is listed for example as
https://www.gog.com/downloads/rebel_galaxy/en1installer0 (
And i assume only works if you have the game in your library thus useless to anyone else, otherwise it's a very bad security issue).
So... The en1installer0 (
note the zero offset/index) to get 10-19 you'd do en1installer9 en1installer10 en1installer11 etc to en1installer18 until you are done.
But that's a pretty bad workaround. I don't have any games on GoG that take more than like 5 installer parts (
And probably never will)
