GOG is slowly introducing new filtering system for store page. I'd suspect the new filter settings have different URL, perhaps you're one of the lucky ones who got access to the new version.

Something is off with their site lately I noticed.
For example, on a store page, you click the developer/publisher and it will open the gog store search with the parameters for the dev/pub included. The first time I click it doesn't, the subsequent clicks it does. Weird small issue but something changed I think.

Does your bookmark resets all the time or only the first time you click on it, and then after a while resets again?

God, this forum is disgusting to navigate and use. I keep thinking I am making new posts, like that button tells me, but it is a comment. And ZERO feedback.

Anyways, I re-made the bookmark and now it seems to stick. Did not stick previously, so there were some problems. But yeah, seems to be "fixed" now, however long that may stick.

I does NOT stick for me, I HAVE to open the link 2 times: first time to see the default screen, second to see my own link.
Same goes for the filtering by company name, I have to click on a company only to see the default page again, then click back, then click to the company again to see the games filtered by that company. This is SO fun!

Uh? New post indeed means a new comment and not a new thread\topic..

reddit thread post comment 4chan thread post whatever, the terminology is blurred and the forum is still clunky.

And yeah, it also stopped sticking for me today.
