Survival Game Kits V2 save system uses the player name to determine which save to load when a player starts the game.
By default this name is random meaning that if a player closes and opens the game or changes level their name will be different, so the save system will not load there inventory from the last time they played.
If you are making a single player game then all you need to do is go to the location shown in the video below and copy the video.
By doing this the system will always use the same name for the player so the save system will always load the correct player save.
