Here is the file with 3 new versions, i've included a lot of features such AH64D Block III, new variants for some russian missiles like Ataka, Igla, Vikhr, enhanced SA19, SA22 Greyhound and Manpads, you can read about them in the readme file, i hope that everything goes well and have fun:

New versions of 1152GWUT: https://1fichier.com/?krs0csj6s4

SA19/22 GWUT: https://1fichier.com/?67tzqvss5x

But the graphics for the weapon haven't changed nor have the payload layout for the different helicopters before take off.

Is there a graphics file I missed somewhere?

You've missed nothing, weapons graphic doesn't change.
