Surrounding disapperance issue

After walking few steps, and turning back the surrounding of that part disappears from where I came from and just shows a cyan blank screen. And that region does not reappear when going inside it.

And reappearance should take place from larger distance from the player, not when he/she walks in it.


No files, tests, or entry points are identified. Reproduce the cyan blank region after walking away and turning back, then trace the surrounding-region loading and reappearance behavior; done means previously visited surroundings reappear before the player enters them.
