Traderoute length is incorrect?
I think the length of this traderoute should be 13
Yep, it should be. I've seen that before, when you add new roads next to an existing "circle" the game does not take the new roads into account...
One year and it is still broken. Really, who tests this thing? You could have unit tests for a lot of cases like this. Do you manually test everything? Heard about TDD? BDD?
Or are you just not recalculating the longest roads for all players after each object is built on the map? Stuff like this should be easy to fix but you are working on matchmaker and useless things before the game functions correctly.
Thanks for reporting. Yes, 13 should be correct. Forwarded to the dev team.
