Metal gear has received a few updates changing offsets to try to stop gamesaves from being modified since SaveWizard added it to their list.
"It was likely removed since
[extremely obvious reason why anyone would want to save edit their game]" If you think having a lot of S++ soldiers is causing anyone trouble, you haven't played MGSV long enough. I doubt players would think twice about a base having a lot of S rank soldiers given how long the game has been out already, and I doubt the Save Wizard devs play MGSV at all. It's still working within the game's rules, and it's only when players do things like massively boosted HP or damage that severely imbalances multiplayer that I can see why they would disable advanced mode
(which hilariously is not the case with Soulsborne despite having both of what I mentioned).
