Since what's displayed is a page, the post link simply making it skip to an anchor on that page, what the forum does for a quoted post is find out which page it should be on for the user by dividing the post number by the user's chosen posts per page setting, so when posts are deleted and a post is no longer on the page it should be on, that happens. And it doesn't look like something that even could be fixable without a rework of the posts and quotes system even if they would care to get into it.

I just spotted two issues in the community wishlist, both regarding searching titles:

First one I couldn't tell what exactly causes the issue, but it's triggered whenever I search for "SENRAN KAGURA Bon Appétit! - Full Course" (without quotation marks), where the search engine will display no results, even though I did manage to find one wishlist for it:
https://www.gog.com/wishlist/games#search=SENRAN%20KAGURA%20Bon%20App%C3%A9tit!%20-%20Full%20Course

Second one seems to be caused whenever the user searches for Japanese/Shift-JIS characters, where the search engine will display all wishlists currently available, and not just for wishlists matching what was searched for, for example:
https://www.gog.com/wishlist/games#search=%E3%82%B3%E3%83%86%E3%83%BBDE%E3%83%BB%E3%83%A1%E3%82%AF%E3%83%BC%E3%83%AB

In the first case it's the é. The 2 wishes for that game use a regular e.

Not sure that characters other than the basic ones are supported actually. Quite sure that's the cause of the second problem, since it ignores all characters it can't understand. And in fact it doesn't display all wishes, but all wishes containing "de", since that's all it can understand from that string.

Right now I can load any library entry except Prison Architect, which produces an endless spinner and never loads in.

Was the exact same yesterday, when they released the new "Jailhouse" version.
Took a few minutes, then it could be accessed and downloaded.
Now, with the hotfix, it seems to be the same issue.

Edit: works for me, now.

No game page loads now, everything redirects to the catalog.

Edit: Didn't last long, at least.

Library counter down by 1 again, this time due to the consolidation of the previously separate entry for the Saint Kotar: Supporter Pack with the The Yellow Mask prologue (and not the main game which probably would have made more sense to roll the extras into).

Doom 3 offline installers are not available.

It must be fixed by now.

Are there other people who have issue with their wishlist ? When I select "discounted games" to filter it, it shows a lot of games not discounted, and some discounted games aren't shown.

Yeah, this has been going on for a while. I really wish GOG would fix this.

Ah, I'm not alone indeed. Hope they'll work on this soon.
Thanks for the link !

Unless it's a "feature", since they now lump together promos and collections, so also call the latter, which may and usually do also include undiscounted titles, sales, and it's clear that it's not a matter of wording the announcements but of how they're dealt with in the system as well. So if the system sees the title as "on sale", it's picked up by that filter. And it may suit them quite fine, to promote whatever they want to promote, at full price too...

Argh I really hope that's not the case. (please not another "Good News" XP)
With the new layout of sale pages, my wishlist was my main way to see the promotions.

But even with this theory there's issue : for example I have https://www.gog.com/en/game/bloodstained_ritual_of_the_night in my wishlist, but if I select the filter "discounted", game is hidden despite being on discount (but I still see the DLCs).

They nuked/hid "just three words" forum game thread after all this time.
