Chat messages not showing up unless I refresh or switch channels

However, just by opening the forum home page and doing nothing, I get at least one 429 response, sometimes 2 or 3, and this is before clicking anything.

As we just chatted over, this is caused by Unicorn requests queuing up, @renato will adjust the number of Unicorns and report his findings.

I wouldn’t be too concerned by either of those issues, the real problem here is that chat messages are not showing up unless I refresh or switch channels: if I switch from a personal chat to another and then back again, only then I can see new messages.

Now this is quite bad. What should happen is that after the backoff period the chat will automatically recover and fetch all the messages since last working polling. You don’t see that? If so that is a nasty bug.
