I play again with Sandpatch grade and i discover that i can't do many scenarios... One time, an other train is coming in front of me in the same way... So... Boum... An other time, i have a red light.... I can't go further... I contact switchman but it's don't work. The response is "Refused. Waiting signal change"... And i wait... And nothing happen... There is issues in all dls and in many many scenarios, i have never seen this, never..
