After the project is opened for about one or two hours, the camera moves to a place very close to the ground and has not been loaded before. At this time, the fine tiles will no longer load. This problem exists whether in the editor or after packaging.
If the project is closed and reopened, the fine tiles can be loaded again, so I wonder if the token may have expired, but I have tried to specify the token I created on Cesium ion in the Cesium interface of the editor, but it still doesn’t work, and there is no LogCesium error in the log
UE version is 5.3, Cesium map is Bing Maps Aerial, Cesium plug-in 2.4 and 2.16 have this problem
