The good or bad mistake

What if someone messed up a few codes of sanses when they're editing the whole multiverse? How bad can the change will do?

Error, the forced god destroyer and also the one of most tallest sans, shrunk, and no matter how hard he tried to fix it, it seems to became permanent and wouldn't leave their normal codes, Not only he gained a short height, he also got a cute, soft, mom side!

Ink, the creator of AU's and one of the smallest sans, along with Blue and a few more sans, became taller. His problem with remembering things seems to get fixed and got a soul. Huh? How powerful was the person to give Ink a soul!?

Now things changed, Error was now loved, now he got a big harem!
