Normal map creates weird shadow

[Yakub]

Like the title says, i am having a problem with my own texture and a normal map created from it.

The problem occurs on thigs and pelvis - This is right where the mesh bends the UV to connect itself.

I am using gimp normal map plugin and xNormal to make them.

Nifskope to render it, the problem exists while playing too.

With normal map
