Max's Render2texuture somehow inverts normal map on 2nd render?! Why?

Mr GetDown

I'm rendering a normal map using Render to Texture's default settings and when I render the exact same scene a 2nd time with no changes, the normal map looks inverted in the viewport. Its only in the viewport as the actual texture result is the same.

Anyone know whats going on?

Ok, i found it. It was updating to the bump map slot and not the bump.normalmap slot.
