I did this too last night.. but then my WW befriending attempts haven't been going well, so knowing my luck that page-reloaded WW probably would have gotten away too haha
Every time I do this I just tell myself these words of reassurance- “It was going to run anyway” It's still painful, just… different painful!
As for my fail- I successfully claimed a wild wolf earlier and- oh, den's full! And so it poofed, never to be seen again :'D Felt even worse because I'd spent over an hour refreshing for it!
