lemmy.ml federation is bugged

Noticed this several days ago. I wanted to be active in this community: https://lemm.ee/c/tf2@lemmy.ml

However, as you can see by comparing to lemmy.ml's own version of the community, lemm.ee is not properly updating comments or point totals: https://lemmy.ml/c/tf2

When I left my own comment on a post there, it did federate to other instances, but it's not being updated on lemm.ee.

I've noticed something similar with other lemmy.ml communities, large and small. Compare:

https://lemm.ee/c/steam@lemmy.ml and https://lemmy.ml/c/steam/

Politics as well:

https://lemm.ee/c/politics@lemmy.ml and https://lemmy.ml/c/politics

And probably others as well. I've checked to make sure my language isn't set to undetermined and I've also tried viewing the communities while logged out.

There's also something bugged about trying to subscribe to any of lemmy.ml's communities. They appear on my profile and feed as a sub, but visiting the communities themselves, I've been stuck on "subscribe pending" for several days. Clicking the button repeatedly to make another attempt to subscribe doesn't work. Not a huge deal since they still show up in my feed, but it might be related.
