ok so i May have figured it out. needs more testing. heres what i did.
remurged the two files making the original main.pak file over write the XC mod files ( the ones by the same name).
then I reset the requirments.txt to what I wanted.
Lastly i used the mod's scripts File (only) to overwrite the one that the main.pak had rewriten previously.
then tested it and it seams to have worked but needs more thoughro testing.
