An occasional crash occurs when adding a sphere reflection capture to the scene from the place mode panel. This issue has a low repro, but has been seen a couple times. Repro rate seems to be around 2/7 times.
Waiting for crash reporter to populate
Result:
Observe a crash as the reflection capture is placed in the scene
