I'm aware that the whole game size is almost 32 gb with the Reaper of souls. I deleted the game and install it again, and now it just install 18gb. When I try to go into the menu it says "Your save data is from a previous version of Diablo III. If you continue, it will no longer work if the update is removed" I don't want to loss my data. So, do you guys know anything?
Diablo 3: Reaper of Souls for PS4 has a unique way of warning the player about game updates. However, this is not a warning that your save data is gone; rather, it is warning you about reverting updates. In the event that you play the game in a non-updated state, your save games will not work.
Your current saves will be converted to the newest update, but if you roll back, those saves will exist, but cannot be loaded. The simple answer is; don't roll back your updates!
