Research direction

Reproduce the OnlineFPS Demo character-death flow with the reported Unity and package versions, then start at EntitiesGraphicsSystem.UpdateAllBatches in com.unity.entities.graphics@1.1.0-pre.3 and follow the update path shown in the stack trace. Done means character death no longer produces the reported NativeArray sub-array exception.
