Sorry if the title is a bit confusing lol idk how to explain it. If I click on a pet in my or anyone else's stables, and then click the back button to go back to the stables, it loads the first tab of the first stable .
The stable list will tell you you are in the stable the pet you clicked on was in, but the stable itself will be the first one. You can't re-click the stable name as it still thinks you are already in it, you have to click a different stable and then back to the one you want.
Not a crazy bug or anything but it is mildly annoying if I am looking through a specific tab or something as it keeps sending me back to a tab I don't want to be on. I don't know if this is happening to anyone else but I've been trying to ignore it for awhile now lol, it didn't seem like a huge deal so I didn't post anything before but it's kinda annoying. : (

When browsing people's stables, the URL doesn't actually change. The page you're viewing is still technically https://www.sylestia.com/stables/ or the url specific to a user, which also defaults to the first stable. So that's what it loads when you hit back. I can't say why the list stays on that stable though, that's odd.

If you want to go back to the tab you were looking at, rather than hit the back button, you can click "View Stables" on the pet's profile and that'll pull up the exact tab

Looks like it's just a combination of how the Stables page is coded and how browsers handle typical form inputs (the drop down menu) when using the 'Back' button.

I would have to somehow script in a solution to this to fix it, I think.

In the meantime, you can just Ctrl+Click or Middle Mouse Button+Click to open the pet link in a new browser tab and then just close that tab when done rather than redirecting and then going back.

Alternatively, you can click the "View Stables" button from the pet's profile to go back directly where it's located at.

I guess I forgot that the stables always did that, I don't know why I didn't remember. Thank you both for the clarification! I will use the view stables instead or move the pet to a different tab. Thank you! ^^
