I thought you can farm

I thought you were able to farm the train on Marcus mercenary hh pack? I beat the snowman and I didn’t turn in the mission. I saved and quit, went back and it made me turn in the mission. Now when I go back the snowman doesn’t come back and the train is gone.what did I do wrong?

You can turn in the quest,save and quit go back to the snowman ring the bells again and when the snowman is dead the train should respawn.

What he said. You have to beat Tinder each time before you can farm the train.

Ok, I didn’t notice the bells. I’ll look again tomorrow. Thx guys
