When I use Advanced Route (RU TO Korea) I have Ping of 210 but Game not run, because game Say I am not in Korea. So Multi-Route not working for me (advanced) And Single Route is Ping of 400, but I know Ping can be 200 
Weird… Then it means the game item of Mudfish has an internal issue. However could confirm that How to check the advanced node option working works fine with above nodes?
