Hi, not sure if this is a VE problem or if it's a tool problem (if it's a tool problem, can anyone suggest where the best place to report this is?).
If you try to add a link from World Rowing, e.g. http://www.worldrowing.com/events/2015-european-rowing-championships/mens-double-sculls/final/ the 'add a citation' automatic option changes it to a link to just www.worldrowing.com. I'm not sure what's causing the behaviour. If you go in and edit it, you can change it to the correct one but that involves spotting that it's done that which might not be obvious to all users.
