Since (apply min <any-coll> 0) is always 0
There's a bug in the code for direct routes that are not over multiple hops.
min-route expects a collection so we should always return a collection.
This way it works for both direct and indirect routes:
(find-path (grouped-routes routes) :paris :london)
;; => {:cost 236, :best [:paris :london]}
(find-path (grouped-routes routes) :paris :budapest)
;; => {:cost 251, :best [:paris :milan :vienna :budapest]}

Maybe this might work better?
(apply (fnil min 0)))

@allentiak doesn't work since min takes variable amount of arguments

Note that how the code was before, for the values of the game-users it will always return a min of 0

Dear maintainer,
Based on inquiries I changed some code. I think it's now more correct. Let me know if there are any questions.
Kind regards,
Erwin
