Sorry, I miss to understand what you are asking then. If you can establish the tavern, you’ll get Nemsy. You can do that whenever you want if you have at least 3 people participating by connecting on the same internet connection.
Answering my own question, you can see progress on the drops at https://www.twitch.tv/drops/inventory . For example, I can see I’m at 25% of two hours on my second pack.

I have had my computer on for the past several hours while having a tab open.
