I should add to the above stuff that it's also risky to use a save editor in some games. Tavern Of The Spear, for example, breaks and your HP goes negative if you use too high a value. So, basically, stats and relationship points, only alter them a bit, e.g. don't put a million in your Charisma. Cash you should max at 90,000, you won't need more.
And love points ONLY go up by 1. Don't put 10 or 60, just increase it by one for whatever you need like if you want Logan to love you but you saved Bernard. Just a bit of advice from someone who edits regularly to speedrun games to new stuff.
