I'm attempting to complete two TGV trainsets, but, I'm having trouble with uploading the final pieces to the sets, they called "TGV Unit 3" in paint shed. My process is that I save the finished rollingstock to TRS 2004 and then import the content folders to TRS 2019. The exact issue is that even though the are two separate assets, the game treats them like they are the same exact asset and replaces one with the other.
