16 module manager errors occurred while trying to apply RationalResources v3.0.2.0 jet family patches (RR_JetFamily_CRP.cfg) to [AAengine] (Engine_ARI75.cfg), [opt_vtol_lpj1] (EnginesLowProfile.cfg) from OPT_Continued 3.4.9.3 parts.
Avoided by removing these engines from OPT_RR_Engine_Families.cfg of OPT_Reconfig to not patch these engines by RR (or to patch based on their families before reconfig changes - no errors occurred).
Another 8 unknown errors were solved by installing OPT_Reconfig_LessB9ForTweakScale.cfg extra.
Unfortunately, I've not saved log data.
