Well I made a quick temporary fix.
Take ETO_incendiary_stick_4lb and change it to TOW_incendiary_stick_2Kg with all internal files correctly name changed
Take pylon SBC_Mk_IA_15 and reanme it SBC_Mk_IA_15_LW with approriate internal name changes for the xdp.
Take an He111H and add a bomb load using
<Loadout Name="2 x 271 Gallon Wing Tanks + 8 x TOW_incendiary_stick_2Kgs">
<Hardpoint ID="0" PylonType="SBC_Mk_IA_15_LW" PayloadType="TOW_incendiary_stick_2Kg" Quantity="32767"/>
etc
Test it out in a missions using Coventry and ETO_City_target facilities
Results for the bombs are successful but There seem to be some effects issues as seen below
Successful bomb drop
Rest of staffel also dropping OK
Note black 'hatching' effect which also flickering; in fact other parts also flickering. In addition that flat circular lighting effe to the left. Looks very artificial IMO. The searchlight with the AA battery needs changing as just goes straight up!
Flickering black hatching effect. I have noted it elsewhere when light/fire involved.
