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.
Nope, I've seen it happen with lemmy.ml and lemmy.world, it could be that it happens more on servers that are under stress.
