From the album: Preview of 1.8
Apparently, aside from adding content, earlier versions of TSLRCM also took a bit of content.
Incorperating Kreia/Jinger's Rebuild Dantooine was good (since it was good) however suddenly all remaining masters dropped dead when confronted. Instead of having to do battle as in vanilla TSL.
So, with 1.8, with the additional kreia content, you still have to do battle with the remaining Jedi Masters just as in vanilla.
I certainly hope that was the only bit of content that got lost due to TSLRCM 0_0
