Why are my game saves corrupt after i used console commands?

Some console commands can alter or affect the game story or load process and can usually cause things to happen when they are not supposed to or they don’t happen at all. Using console commands to complete all quests or all missions can cause the game to get wacked out and cause it to cause system errors or even crash. Games that have corrupt files usually cause the game to crash or freeze. In some cases it might not let you go back to that save file to prevent it from crashing or freezing again. That is why it is recommended to see what the console command will do to your game after using it to prevent any corrupt or unplayable game files. After the game files are corrupt they usually cannot be played again unless you saved your game before using the console command. It is best to save your game before using console commands to prevent this from happening.
