Also I faced another problem. While playing the latest version I saw that the file saves from the prev version didn't carry over and I have to start from the beginning. Isn't the file saves supposed to carry over?
File saves from previous versions should carry over in most cases, however cheats and secret codes do not. So if in your save you used cheats from secret codes for example some of those cheats will get reset and valid secret code for current version will be needed to activate powers/cheats again. 👍 Thank you for the earlier post, I will consider your suggestion about unlocking the content later down the line. 👍
