The characters shadow can appear disconnected from the player. This happens mostly when you are on top of a high hill, and the sun will be shining on your character.
Instead of creating a long shadow, like the sun should, you can see the shadow of your characters body somewhere on the environment on the area the sun is shining. This shadow would be disconnected.
There is also another glitch that happens with these types of shadows. The disconnected shadow can make another disconnected shadow on an object behind it, and it would make another disconnected shadow, penetrating through the first object as if it wasn't there obstructing the second. {F18854}
