I created a menu item with alias 'sci-fi-offer' and the full path /fiction/offers/sci-fi-offer. I changed the menu item to an url for the time being and it looked and worked all fine but I got some weird URLs in Webmaster and on further investigation found out that I could still put the url 'site.com/fiction/offers/sci-fi-offer' and instead of showing a 404 as I expected; I get a page with the list of categories as follows:
uncategorised(22) - (Linked to: /fiction/offers/sci-fi-offer/1-uncategorised) sci-fi(14) - (Linked to: /fiction/offers/sci-fi-offer/3-sci-fi) drama(12) - (Linked to: /fiction/offers/sci-fi-offer/5-darama) autobiography(7) - (Linked to: /fiction/offers/sci-fi-offer/7-autobiography)
Those are all categories and the number of articles are in the brackets. The categories all have links but none of those links are correct. Could anyone point me what the heck is going on here?
