I recently got the RWA Modern frieght, I have some repaints for the 100ton coal cars. Whenever I place the repaints into a scenerio and try to couple to them I get something bad has happened error. If I try to edit the scenerio, it won't let me remove the cars and I have to delete the scenerio. I did find a couple of cars that were invisable except for the couplers. Any ideas on how I might fix this.
All the RWA cars work fine only the repaints have issues.
