Im horrible with them too but that has been a thought. I can still talk to both of the members, its just as if they decided they were sick of following me around. Its not as bad as some people except they are my favorite characters to run around with. I don't think any of my mods have an effect over this one neither. Its odd thought because I thought the Red Eclipse event bug on Nar Shadda was patched, than again there might still be a click somewhere, I was running around the landing area with Mandalore and HK-47, I did the quest once and decided to force the Red Eclipse to join me. I went back out and ran back to the refugee sector and bam the same cut scene again. I ran back to face just 4 of the Red Eclipse guys, killed them and found my empty ship. I then closed and used my trusty save editor to fix that but upon returning my HK-47 and Mandalore were no longer able to join up with me... ):
