* About Korriban; did you fast-forwarded in their cutscene? They might linger a while if you pass lines, but should never stay permanent. Did they fade-away eventually.
The only "fix" would be to make the last few lines unskippable. Not sure people would really want that to fix a minor display issue that fixes itself pretty fast...
* Can't fix the door closing issue. People reported it before (in the beta), but trying to undo that just does more harm than good.
* The infinite stock is intended. However having 2 of the same type wouldn't be...
* I'm always getting droids confused. I suppose Zbyl and the rest does too from time to time. If we really typed IS-18 where it should be IS-02 I am sure it'll be fixed in a patch.
He's completely removed, so that cannot be the case. I think you have a conflicting mod there :/

Yeah, the exile needs to be loaded into the module, otherwise the cutscene can't play. Might be able to cover it up though, as I did for 1.8's Nihilus/Tobin cutscene, shouldn't be too hard...
* The solid holograms are intended. Otherwise they wouldn't make good target practice (the explenation I got from Zbyl when pointing this out).

* The "shoot through wall" issues in the Environmental Zone can't be fixed. OE didn't really have time for hitdetection, and modders can't add it in. You'll notice the same happening on certain locations in the HK-Factory in TSLRCM. Just something we have to live with, and we can't fix OE's rushing...
