Appears to be a UI problem, since like you said, that shouldnt be blank.

Have you tried reinstalling the DarnUI fomod or disabling 1PipboyPDA.esp(haven't used that mod, wouldnt know if that would effect this or not)?

You should also disable T3T_MiscItemIcons.esp btw since T3T designed all the new FWE icons anyhows.

Reinstalling Darn UI, the hotfix and the FWE Dui patch, and disabling T3T seems to have worked, cheers kai.

PipboyPDA is by Alexscorpion, used to be available at FOnexus, but he longer hosts there, instead its on filefront.

Quite a handy mod, especially for alternate starts.

1) Turns the pipboy into a PDA
2) Removes the "pipboy" from the third person view of your character which is quite handy.
