I have downloaded and installed (or so I thought??) the historic ballparks for OOTP 18 via Steam Workshop. When I try to go to Team Settings the ballparks are not there. I tried creating a new MLB league 2 different times hoping they would show up. I have the files on my hard drive and have seen all the folders for the various seasons. Is there some sort of trick to making them show up in OOTP 18?
