The part was that they showed, Aryan taking the gold chain and pocketing it, Boxer, Ajay, Zubin and all moving around in the office, when a new case comes in, was shown in the earliest episodes of SS, probably the second one or something, Shaina and Pappaji were also a part of that scene but since they weren't a part of the SS anymore, the scenes that had them were edited. The SS sets did catch fire when the show was nearly winding up, the episode of Koh-i-noor that you are referring to is something I also saw and pondered about, and my guess is that maybe those shots were canned earlier (as far as my knowledge goes, Koh-i-noor supposedly wound up in December and those shots appeared to be of the earlier part of the show), I have no idea of when that episode was telecast since I saw the whole of the show at one shot or that the set was recontructed. When I saw that episode, what struck me more than anything else was why UTV had leased out it's sets to another production house, UTV is a media biggie, and Koh-i-noor was produced by another production company, so why would UTV give it's sets out to another company for it's shoots? This question is still left unanswered. But, yes the sets had caught fire. Gauri's interview in the Mumbai Mirror/Bombay Times mentioned it. If I do manage to find that article then I will surely give you the link to it.
