Gentlemen, I have downloaded the activity and after installing it, I have found a slug of missing cars. I have the required downloads listed all previously installed. For instance; RR says Faulty activity klw-pk-oil cans west pt 3. act is missing Wagon US@FREIGHTCAR1\us2freightcar1black_empty.wag. Also these same cars of which there are black, green, blue both empty and loaded. These are not the default cars because I have looked. There are a number of loose consists that contain these same cars that show as missing. What did the rest of you do to relieve this problem? I can swap them all out with ConBuilder, but feel that I shouldn't have to. Thanks for any help.
