Thank goodness for that. Why would we need Sebring 2018, 19, 20, 21,22 when they are all the same layout, same surface, just the billboards are different? Create the WEC pits, Add the Historic longer circuit by extending the run to Turn 7 down by the hotel. Those are changes that make a difference. I can't recall ever looking at a billboard and going,..."oh look! 2019!!!"
Adding a bit as I DO sound harsh. That was not directed solely at the OP, it could any number of 3rd party edited tracks, There used to be dozens of versions of certain layouts simply due to one user not liking the color of the grass or the signs or whatever. I don't want to discourage folks learning to do more, since I CLEARLY haven't for years. My animus may go as far back to my days simming with the Papyrus/Sierra titles when all the modders could do was alter the signage. My appologies for targeting.
