Wherever I try to save an achievement to my saved achievements list, the achievement tab refreshes and it shows me different achievements. I don't even have the retired achievement in here. It goes away when I refresh the bug page, but this makes saving achievements in masse pretty annoying.
It not only happens in here, but also on every achievement tab.
Operating System: Windows 10 Navigator: Firefox (up to date)
Seconded on up to date Firefox, Windows 7 I genuinely had no idea what the checkboxes were even supposed to do, because checking one will jump me to a page with some random achievements, including 'Only Have Room For One' being marked as Earned (I do not have that one)
I tried on another PC (one of the PCs on college) and I get the exact same glitch.
Ohyeah, it freaks out like that in Firefox. :'| Works just fine in Chrome though.
Tried con Chrome mobile. Glitched here as well.
I tried in Chrome for mobile and on my PC just now and it worked for me? Though I did have to zoom in super far on mobile to only tap the checkbox and not accidentally tap the achievement name/link that displays the achievement.
It's the same with Chrome for desktop, it can be super fiddly, but it just plain refuses to work in Firefox. I wonder... Maybe it would work if the checkbox was separated from the link a bit more? They seem to almost overlap now which makes it super fiddly to add/remove achievements to your saved achievements list.
[edit]Link to screenshot, because it was 2big, was not auto-resizing, and I don't want a warning.
Screenshot was taken in Firefox. The link and the header extend allllll the way and cover the checkbox. Which is possibly why things get super weird and glitchy in Firefox. Chrome probably interprets the code a little differently, but that's just my guess on what's causing this. :'D
It might be a glitch related to my account only. So I might need a dev's help.
@ Iara ? I wonder...
Quick questions: Were you in the "Basic" achievement category when you were adding achievements to your saved list? Did you get redirected to only seeing the achievement you were trying to add to your saved list? (For example: the Vending Maniac one) Did you go click backspace or the left-arrow in your browser to back one page after that?
Because I've done all that, step for step, and it's redirected me to the page in your screenshot without fail.
[edit]Sorry if I seem pushy, the achievements page is buggy to all heck and the more info both of us can provide, the better.
Yes to everything. Also clicking other categories after getting away of the achievement that redirects me shows me the same image.
@ Iara If I go to the Basic category again, click the checkbox to add the achievement to my saved list, but then click a different category to go to instead of clicking backspace (I went with the Items category), I get this show of achievements.
If I do all of the above, but manually click to go into the Basic category, I get the same image in your first post. I can tell you 100% that it's not your account that's the issue.
I've tested it again and it works in Chrome (desktop & mobile), but you do have to be super precise with ticking the checkbox.
Here's the thing: if you click any of the achievement names without touching the checkbox, the bug can be replicated. Go into the Basic category, click the name of the Capture A Lizard achievement, then click the Basic category again, or hit backspace.
Edited for clarity.
It also screws up in the other direction - when you remove achievements from the saved list. It is extremely glitchy. Can't reload the page, can't use the back button and I've also gotten weird results when I try to "open in new tab" for any link.
One more thing. Once its become glitched, I have to actually close the tab because if I try to go back to the main achievement page via the menu (not reload or anything, directly from the menu) that doesn't work either. Its like it gets lost or something.
And yes, I'm in firefox and this issue has existed through many, many versions of firefox.

Some things really don't seem well on my achiev page too, I think it's a general glitch.
Gourmand Feed different unique foods to one pet! [50] [100] [150] [250] [500] [1,000] [1,500] [22/ 2,000]
And when I click it, its counting resets to zero.
Also several wadrobe achievements only count their progress when you actually go and refresh the wardrobe and then go back to achievement page and click said achiev title.

I just tested this out and it all seems to be working as intended on my end. Can someone confirm it before I mark this as resolved? :)
Pinging again/waiting a bit longer before locking as resolved. :)
It seems good to me. Removing checking marks, moving around after working on saved achievements, toggling the checkmark, etc all seem to work as they should. The page no longer seems to "get lost" and my achievements list correctly as earned, unearned and how far along I am.
And I earned 2 achievements while testing! Yay!
