Hey patson, I'm not exactly sure what I've done, but I was just able to open two routes without using any delegates.
I've opened a first route, just normally using 4 or 5 delegates. Then I wanted to create a second route with seven frequency, but I did not have enough delegates for that. So I canceled the "negotiation dialogue" and reduced frequency. When clicking "create" then, the "negotiation dialogue" did not show the negotiation part, just the comparison part (prices, frequences, etc. before and after) and I was able to create the route without using any delegates.
Thought I'd let you know...
