Okay, I encountered this thing the first time I was going through the game, so I started over because I heard this is a bug that sometimes comes up, but...

I have encountered it again, so my question is: is the galaxy droid supposed to appear and if so, when. I have encountered it both times the first time I get to walk through the hawk after we escape from Malak, but it also seems that in both cases, my game had that load error when trying to load up a planet after finding that thing. Heck, last night, when I saw it on the bridge, I ran the other way (literally) without talking to it, but the game froze on load up when I tried to disembark.

Also, when everyone was in the central room after the revelation about who "I" was, I could not find juhani anywhere, she wasn't in the room she's been in. Any ideas?

No, it's not supposed to happen. I recommend you post this in "Ebon Hawk's Machine Room" for technical questions. you might also check swforums.bioware.com for some possible answers.
