ErRoR (medium)(Main)

The ErRoR badge should actually be easy, not medium.

It is found in the town of F.R.I.E.N.D.S. (The place where you spawn.)

You will need to get over the walls. Even if you put one of your limbs over the wall you may get teleported to The ErRoR badge.

The ErRoR model could be the same to 1noxy's ragdoll simulator's model. It is found in the unused map "Tower".
