Some instances spawned by NeagaraDataInterfaceChaosDestruction breaking event will be set location to the world origin

 The following code can often be found in UNiagaraDataInterfaceChaosDestruction.

		const int32 ParticleID = ParticleIDParam.GetAndAdvance() - LastSpawnedPointID + 1;
 

The LastSpawnedPointID is usually set to -1, so the iteration range is over a range of 2 to GetNumInstances()+2 and references an outside the range.

The following code can fix the issue :

		const int32 ParticleID = ParticleIDParam.GetAndAdvance() +LastSpawnedPointID + 1;
 

1. Open the attached project (This project includes a GeometryCollection and NiagaraSystem with a standard setup)
2. Start PIE
3. Observe the world origin

Result

Some particles are spawned at the world origin instead of the breaking event location
