yeah there is good chance that you are sadly, but thats the risk with mods or any kind off variable manipulation
i can garantie that is safe to add money and talismans (those only after you got it, to be safe after you gave 1st to priscilla) via onlinesave editor , i had no issue with that, anything else is long known that can break your game.
just check which % you are and grab same save here

make fresh save ingame and replace it (you have to replace existing save) with this one, after you can change name for 50 bucks in store
1st do try and go in store and click around , there is chance that is invisible, apparently has happened before
