 ##### Fixes :wrench:
 
 - Fixed a crash that could occur when using `SampleHeightMostDetailed` on a `Cesium3DTileset` with a raster overlay.
 - `CesiumPolygonRasterOverlay` now references `CesiumCartographicPolygon` instances using `TSoftObjectPtr`, which allows, for example, a raster overlay in the persistent level to use a polygon in a sub-level.
+- Fixed a bug that occurred when a `Cesium3DTileset` had three or more overlays.
