just now i tried to change the affinity slider to non-sticky behavior, as it was earlier, but that does not seem to work.
in /settings/featured --> affinity slider the option "Always reset on new page visit." is always enabled, even after saving it with the "no" option. and my stream behaves accordingly: it always retains the settings i manually apply, never reverting to the default settings from the settings page.
actually, those default settings are updated with every change i make to the slider on the /network page, without ever saving those defaults in 'settings.' this does not look like intended behavior.
(i'm using the original 'dev' code of course, not the branch i use to make the slider an 'app.')
since i had to dig into that code already i may be able to figure out what's happening, but not in the next few days. and i guess you will find the reason faster than i could; let's see...
