Posted this to AskLemmy (https://lemmy.world/post/17088629), but thought it worth posting here:

I use old.lemmy.world as my interface and I've noticed that roughly every month I'm:

• Forcibly logged out and have to do the re-auth dance for no apparent reason.
• Everything I've set in Settings is forgotten: Default Listing reverts to All, Default Post Sort reverts to Hot, and so on.

My browser is set to retain cookies and such, so it's not PEBKAC/PICNIC. Why is Lemmy doing a nuke-from-low-orbit every month (roughly) despite me using it as recently as the day before? Why aren't my preferences being retained between logins?

I suspect the recent update (https://mastodon.world/@LemmyWorld/112706805419064266) explains the latest event, but the questions still stand.
