Hi, BenWoodhouseEpic(https://github.com/EpicGames/UnrealEngine/commit/99299c23efdbc8e5e867dee9508a75c434b18125)

After update our project from UE4.15.1 to UE4.15.2, our old level will crash when adding it as a sublevel to the other one “Persistent Level”(By Levels->Add Existing).

After many tests, we find that the bug is in the “SphereReflectionCapture” actor. Our old level has one “SphereReflectionCapture” actor. When we click the button “Update Captures” (int the details panel of the “SphereReflectionCapture” actor), our UE4 Editor crashed.

And the errors are something like this:

Hey yehaike,

I have a few questions regarding your crash:

  • Could you please provide the logs from your project’s Saved->Logs folder?
  • Are you getting a crash reporter window? If so, please provide the Login ID as well as ensure to hit Send & Close
  • Can you reproduce the issue in a clean project? If so, please provide a detailed list of repro steps so I can test it on my end.

Thanks

Repro steps:

  1. Open this UE4 project with UE4.15.2

  2. Open the “MAP_001_SphereRCBugDemo_Main_01” level.

  3. Select one “SphereReflectionCapture” actor.

  4. Click the “Update Captures” button in the “Details” panel.

  5. Wait for the crash of UE4 Editor.
