Describe your issue

So this is a pretty rare bug to encounter, but lets say you add an emote at around the same time, exactly one day ago, and add one now. The is:system message will be grouped with the one from the day prior, instead of creating a new one, making it seem like no EventAPI message was sent and not chatterino wasn't refreshed (when there are logs), but it did.

Exact timestamps

query

{user(id:"6438bc16e06ecb731b237a8c"){activity(limit:2){changes{array_value{added updated removed}}created_at}}}
