I have a curious bug to report.
At some point in the past, when we disabled, removed and then later reinstalled babble, the chat channel topics vanished entirely from regular view. They're not in /c/chat and they persist even after being "deleted" via the Admin "Chats" page.
Now, it's causing interference with the Topic List Previews plugin, but cricially _only for admins. Not myself, who holds the "developer" credenetials, just for the other two regular Admins.
Line 88 in https://github.com/angusmcleod/discourse-topic-previews/blob/master/plugin.rb is where the error happens.
What I'd like to do is track down these weirdly-behaving chat topics and wipe all traces of them from discourse. I have no idea how.
I ummed and ahhed about which topic to post this in acutally.
@angus - have you ever seen this error with Topic List Previews?
