Sorry, my English is not good

environment：C++ Project 、 UE5.5.4 、cesium for unrealv2.16.0 from FAB  
step：

1. C++ create ACesium3DTileset and Add UCesiumWebMapTileServiceRasterOverlay Component (connect WMTS server)
2. call RefreshTileset() function error crash,Or the second call error crash

unreal editor works fine,Run crash after bundling

I have been troubled for a long time, please help me,thank!

@Yuan_Yao Thank you for the bug report. Do you have any further information - a log to attach or an error message? It’s hard for us to figure out what might be causing this error just from this information.

I used the first map from the CesiumforUnrealSamples project, changed “Source “from” WorldTerrain” to “FromEllipsoid”, pressed “1” to call “RefreshTileset”, and Package the project.  
Crash when called the second time.  
I suspect something to do with FromEllipsoid.

@Yuan_Yao Sorry for the delaying in responding, we had a long weekend this week so I’ve only just gotten back to the office.

I was able to look in to your crash and reproduce it with the steps you’ve described. I’m still trying to figure out what’s causing it, but I’ve drafted up [a GitHub issue](https://github.com/CesiumGS/cesium-unreal/issues/1682) to keep track and make sure we tackle it.

Thank you again for the bug report!

I’ve managed to track down the source of the bug, and I’ve made a pull request with a fix that you can find [here](https://github.com/CesiumGS/cesium-native/pull/1192). This fix will hopefully make it into the next release of Cesium for Unreal, but you can follow [the developer setup](https://cesium.com/learn/cesium-unreal/ref-doc/developer-setup-unreal.html) to build your own copy of Cesium for Unreal with the `ellipsoid-tileset-raster-unloading` branch of Cesium Native if you want to get the fix now.
