Describe your issue

Occasionally, newly added 7TV emotes don't show up in the chat, requiring a refresh for them to show up. This issues doesn't seem to be present in the Chatterino2 version. Opening up the Debug screen doesn't seem to provide any meaningful readings.

Additonally, when starting up Chatterino7, 7TV emotes that were loaded from message history don't render (refer to Screenshot)

It would be helpful to know if this only happens once or if all added emotes in a channel don't show up after one fails.

Both Chatterino7(tv) and Chatterino2 make no effort in synchronizing message history and emote loading.

Emotes not showing up is VERY inconsistent, sometimes it happens just one emote out of a bunch, sometimes multiple in a row don't appear, hence making testing very tricky

I'm pretty sure the issue is that when you reconnect a connection, we don't subscribe to all the previous topics. But I haven't been able to reliably reproduce this.

Funnily enough, I haven't been able to reproduce that bug in Chatterino2 at all. Tried many different methods, to no avail. So SOMETHING is being done differently there. As I have no real experience with coding, I couldn't tell you where to start looking though, sorry.

Tried many different methods, to no avail.

So which method works on chatterino7 but not on chatterino2?

Normally adding emotes one by one, just like you would in a normal scenario. "Hey 7TV Edtior, please add these 5 emotes", and 2 of them randomly don't show up in Chatterino7. It's also very inconsistent between users, one emote gets added for me, and it doesn't get added in another user's Chatterino7.

Looks like Chatterino2 has the same problem. I think this has something to do with the 7TV eventapi, because you can also notice issues in the browser where it doesn't confirm that emotes are added (e.g. when adding/removing emotes by right-clicking). If you reload the page, it properly shows the result.

You can also run into this when you just connect the eventapi without Chatterino's stuff.

So basically this all goes back to 7TV's shitty API. Lovely.
