Ah I missed old.reddit. I guess I'll be using that from now. I had a constant problem on the default frontend when hitting 'back' it would show All instead of local or subscribed.
Yeah I have that issue too. It shows whatever was set when the page was loaded. If you choose say Local then refresh, then when you go to something and go back it will be on the Local tab.
It's pretty annoying, and I think only a new bug introduced in the last couple of updates. Maybe it will be fixed in 0.19, which should be not too far away (though I haven't heard any specific timeline).
It's not really a work around, it doesn't help. If you go to the next page, then when you open something and go back it will be on the first page you were on, etc. I guess the best option at the moment is just to open things in a new tab.
