chat-downloader: [BUG] Downloader thinks it has finished retrieving chat on the second request on member-only streams

Basic information

• Program version: 0.0.8
• Python version: 3.6.9
• Operating system: Ubuntu

Describe the bug

I’m trying to get the livechat from an ongoing member stream. The downloader outputs to stderr [INFO] Finished retrieving chat. after the second message batch, then the program closes.

I’m not yet sure if member-only is the cause, I’ll keep trying on subsequent member-only streams I have access to.

Command/Code used

If running from the command line, provide the following:

1. The command used (including the verbose tag, -v):

chat_downloader "$URL" --cookies cookies.txt -v

Expected behavior

Downloader keeps outputting new messages as long as the stream is live.
