I tested this on multiple browsers and systems. Our All/Hot has been like this for 2 days. If I leave it long enough, multiple minutes it will sometimes load a bunch more and get stuck in weird update cascade that will use up all my RAM.
None of the other instances I tried have this issue. It seems to happen whether I'm logged in or not.
I actually have a lemmy.world account, but it's so laggy, I can hardly log in.
