Hi. Go to your program files, find ts4- in those file you want the folders, data and delta.
Click on data, then shared. You’ll see a folder called worlds, all the files in there need to be replace with the ones from my download.. In my download you wanna take the files from the one titled base game, copy and replace.
It’s the same thing for delta, except all of those are broken down per expansion and game pack. To replace them find the corresponding folder and copy and past.
I really hope this helps, I’m shit at explaining things, but if you have more question feel free to shoot me a DM.
