Lobby takes forever to catch up after returning from a battle

[bbbccd]

duplicating from here because i was told this is the place for this

Description

The lobby seems to be slow after returning from battles recently. Like maybe it used to run in parallel, a couple weeks or a month ago, but now it seems like it has to catch up on every interaction it has had with the server in the past half hour.

Expected Behaviour

It used to be after a battle you could chat with people reasonably quickly.

Actual Behaviour

Now you wait and wait for everything to catch up. Thinking back that "forever" is maybe 10 seconds. It prints all the in-game chat and votes. You can watch your friends list and it will keep updating which map they are playing as it cycles through everything that happened while you were gone in battle. Available games come and go.

Reproduction steps

Play multiplayer game. Finish game and leave. Wait as everything catches up.
