Polygon Gone!

I was going back and forth between Unity and Maya testing the texture I was painting to see how it looks in the game. Everything was fine but all or a sudden, one polygon on the chest of my character disappeared.

I checked the normal of the polygon and it's fine. I double checked by turning on double sided on my shader and it still does not show.

My texture does not have an alpha or transparency at all.

 

Nevermind, I must have deleted an edge by accident because it had 5 sides.
