Like the title says, if a thread you have subscribed to gets deleted, it still shows in your list of subscribed threads... hardly very important but there we go
Here's what I did:
1) I created a test thread
2) I subscribed to it (and confirmed the subscription)
3) Deleted the thread
4) Went back to thread subscriptions and the subscription wasn't there
I can't reproduce it seems
can't reproduce here too.
Actually I think it got moved, I got a no perms page rather than a thread does not exist page.
