I think that CG was used in the built before this one. I found a video https://www.bilibili.com/video/BV1ZKB7YjEnp/?spm_id_from=333.337.search-card.all... and on minute 21, the 'Hug' CG was used. Perhaps they rewrite the prologue and changed some CGs, bcs the layout look quite different than how it is rn. As for the loading, I haven't found where it was used either
