KeyError: 'member'

There are no threads in my server, at all. No one made a thread, I’m not sure why there’s an error in threads.py.

Issue seems to be here in threads.py. I left my code running overnight and the error happened relatively early (an hour in).

Code

No response

Expected Results

Code supposed to run for extended periods of time without erroring.

Actual Results

Code errors for unknown reason at random times.

System Information

discord.py is a requirement, which is a library I don’t plan on installing.

I was a little busy the past few days, but I’ll work on it today. The fix isn’t as easy as I thought because thread events (specifically create/join) are slightly broken and I need to fix those too.

Loons like they made the member key a member object instead of a dict that holds a member and presence object. Pretty easy fix. I’ll commit later in the day.
