Someone took the first option of 6517 and created a branch that ties into itself. Why? What is possibly going through their mind? Is it -so- difficult to enable the extend option?
I imagine that it was the same person as before, which suggests that it was deliberate. It's pretty pointless, as anyone wanting to take the tied off option from 6517 could simply duplicate that option. However, as a point of principle I've enabled Add New Option for the sabotaging episode.
