A Bug That doesn’t let me advance – Tiny Rails Review

So I’ve Been Having This Bug Or Glitch, Which The Bug Or Glitch is That I Am In Europe West And I Completed All The Tasks accept one which is Travel to 15 cities but I have 14/15 because whenever I go to a Europe west city it doesn’t count I will just stay 14/15 so I don’t know if this is a bug or glitch. It Would Really Mean A lot If Guys Could Fix This.
