Fortnite props disappear when entering spatial loading range (collision remains)

Summary

In project, some Fortnite props are visible from very long distances.
However, when the player approaches them and enters the spatial loading range, the props suddenly disappear.

The issue becomes more obvious with purchased props (Tycoon gameplay):

Props are visible and work correctly while the player stays nearby

When the player leaves the area and later returns:

The collision is still present

The props are invisible

Happens only in this project. Same props work correctly on a fresh/new map

Affects Fortnite props only (custom assets not affected)

Appears to be a project-level streaming or data layer state corruption
