I was unable to reprogram the HK-51s, when I pressed the "[core console] upload HK-47 protocols" or whatever in the HK-51 terminal, all it said was something like "Error: unable to contact with receiver". I had to setle with simply shutting down the factory, and so later at Malachor that Goto screwed me good... I was really hoping for HK to kick his round ass.
I tried downloading the HK-50s protocols but that doesn't seem to give me any new options either. What chain of events at the factory would need to be followed so that either the 50s or 51s ally with 47?
I'm using version 1.7 + fix and the USM installed through your patch if that is any help.
