OK, so after some tries in the researchRuleStatus: to disable cats, the strings to be present for the cat path to be disabled are:
STR_CAT_PATH: 2
STR_CAT_PATH_PREQ: 2
while to have gals enable, need to have related ones are:
STR_GALS_ARE_SUPERIOR: 1
STR_GALS_ARE_SUPERIOR_PREQ: 1
Edit: whereas: 0=not discovered/active 1=researched, active 2=disabled not researchable. Please correct me if im wrong!
