If someone is still having problems when saving, create a folder in the main directory of the save editor with the following name "GTSaveData" inside this folder paste the dll "GT.SaveData.dll" that is in the main directory of the mod. Create a new folder inside "GTSaveData" with the name "GT6.SaveData" and place your save that you want to change inside that folder so that the final directory is: "[...]GTSaveData\GT6.SaveData\BCJS37016- GAME6". I did this on 7/5/2023 and the save worked. GG guysYes I was.
