I am getting constant crashes in the same area, the whole game freezes and then crashes to the Xbox dashboard. I have already reported this over 3 years ago (October 2017).

I managed to take a screenshot on my Xbox and recorded the co-ordinates where it crashes in the same area.
111, 122, 645
132, 83, 683
114, 97, 725
130, 89, 692

All this has been going on since I entered the beta programme at the time to test the game before it was released to everyone. I was testing the /clone of a large build and ever since it keeps crashing if I enter that area, but sometimes it can be quite a few minutes before crashing again, maybe because it crashes whilst attempting to save in that area.
