but in reality, administrators should be deleting the whole topic, not the only post in that topic. When you delete the only post of a topic, what are you expecting to be left over?

Yes, it’s a case of user-error finding a bug that should be caught. The code should say ‘hey, this is the only post, he must mean delete topic’ and move on, or the ‘delete post’ option shouldn’t even be there if it’s the only post in a topic. You’re both right Code should know better, user should read more (and FWIW, I made the same error when I was testing bbpress).
