I was trying to rewatch yesterday's stream, but it turns out it was corrupted and the last third of the stream was a frozen image of stopped MBTA stock. I tried this on both Chrome and Safari browsers, no luck. Although this isn't a big issue, it might be something for whatever team does the streams to check out. Here's the link for those interested.
Were you trying to watch the Youtube one, sometimes best to re-watch the Twitch stream when that happens.
