I recently went through these exact pains trying to contribute to a project that exclusively ran through Discord and eventually had to give up when it was clear they would never enable issues in their GitHub repos for "reasons."
It was impossible to discover the history behind anything. Even current information was lost within days, having to rehash aspects that were already investigated and decided upon.
That's a worrying sign for a project.
Did you clone their Git and start tracking issues there? ;-)
It's the "see no evil" approach. If you didn't report the issue while the admin was online, then they aren't compelled to do anything about it. Convenient for the project maintainer who doesn't actually like maintaining things. Awful for the rest of us.
