Have you put the background mod at the VERY TOP of Mod Manager?
Did you read the following when you DL'ed the mod?
Also, did you read this, which relates to all the ATS Universal BGs?=====> If at any point the game crashes when entering the highest zoom level in World Map view,
=====> download the following fix mod.
=====> Crash fix mod: https://drive.google.com/file/d/15X_vht ... sp=sharing
=====> Place this mod right above the main BG mod!

To remedy that I made a fix, which you can download here, unzip, and place right above any of the ATS BGs. Here is the link.
