Started world hours ago came back with many missing chunks and half my base missing

I Created a world using the Mesa Plato seed hours before. I took a brief break and rejoined the world via remote play with none of my inventory, and the texture packs (city and, natural) that I had previously applied then deactivated, were reinstalled. I was also fully reset. I decided to try the world on the actual Xbox ware I had all my stuff and was in the same spot although the chunk I was in was missing along with the vast majority of my base.

I was playing on a relatives Xbox, on my account. My Xbox one s is on 2106.611.205 but his Xbox one x is on 2108.210.630-2200. 

I was remote playing to my Xbox one s. But I made the world on his Xbox one x.
