Ununpentium

I'll try to put this short. So after a long time I've decided to install and play KOTOR 2 and the new TSL RCM again (last one I played was 1.7 I think few years ago). But before I do so I need to have some things clarified that bother me ;P I read FAQ's, what's restored and what's not etc. but for some reason I could not find any explanation as to why this is not included in tslrcm. I remember seeing that on YT some time ago and I was 100% certain this has been already restored in 1.8.4 by now. Just as it happened to Nihilus and Tobin scene which at first was not added to tslrcm but eventually ended up in being a part of it so I don't have to use a mod that restores this scene any longer as it is now a part of tsl rcm. So I am wondering, why isn't Nihilus vs Sion scene in tsl rcm yet? Was it even ever going to be on the first place? Is there any reason it's not included? I searched throughout the forums and couldn't find any info regarding this matter, the only thing I could find apparently was an Extended Enclave mod that indeed restores that scene and some of the other lines but again, this only generates more questions than actual answers. EE seems to adjust TSL RCM pretty well so if this EE is compatible with TSL RCM and was supported by zbyl (as I've read in credits) why aren't these two (EE and TSL RCM) combined? I don't understand why is it a separate add-on for tsl rcm when all it really does is simply improve minor details in a good way. I would really appreciate if somebody could clarify this for me in a reasonable manner^^. Thanks in advance!

I'm about to give TSLRCM 1.8 a try. So far I've played only the TSLRCM version 1.7, From what I remember from 1.7, I did not have any problems with encountering HK units - even though I didn't talk to HK before first one (on Telos I think) because I couldn't get parts to activate him so soon. I'm not sure but I think I talked to HK-47 only after activating and right before going to the HK factory. If there's some glitch that makes game unplayable and require editing some lines in files it seems a bit improper... I thought it's all linear about getting to the factory itself, no matter if we talk to HK or not we are going to end up there. Has something changed in 1.8?
