Unable to comment because 'body is too similar'

While replying to a thread, I received this error:

But when I check the thread, my comment hasn't actually been added (or at least it's not showing up for me). Was curious if anyone else has had this issue.

Update: Crap, I managed to reply to the thread after posting this. How do I delete this post? :sweat_smile:

Looks like Flagging :triangular_flag_on_post: is the only way to delete a Topic as a non-Admin
