Updating ytd for fragment yft doesn't work
Using Open IV I extracted C:\Program Files (x86)\Steam\steamapps\common\Grand Theft Auto V\mods\update\x64\dlcpacks\mpapartment\dlc.rpf\x64\levels\gta5\props\mp_apa_yacht_flags.rpf\apa_prop_flags_yacht.ytd using "Extract to open formats".
I made an alteration to the Argentina flag (using GIMP with a dds plugin).
When I import back in using Open IV's import open format tool the ytd shows as being updated.
However the fragment file that (I presume) corresponds with it: apa_prop_flag_argentina.yft (in the same rpf) is unchanged.
Where am I going wrong? (I've tried editing the ytd directly using Open IV also - replacing the relevant flag with a simple jpeg - again - not working).
