Symmetry Bug Promblem

Not sure if i can replicate it. I will try, but I will need some time to do it. The other thing that was done is I simple merged the eye ball and somehow I accidentally vowel it with the face. I did do alot of tweaking using move, clay, smooth, flatten, crease, mask, selmask.

When I worked on the face, setting was how it was defualt, when it happened I changed the world to local trying to figure out what happen.

Say if it wasn’t perfectly symmetrical, should it still work? Wouldn’t Sculpting be out of place but still sculpt symmetrical.
