for supplying the project. I have found the issue and logged a ticket here: Unreal Engine Issues and Bug Tracker (UE-43497)
This is due to the particle bounds not updating correctly as it is probably referencing the Actor’s origin location rather than the moved component’s location. There is a pretty simple workaround for this.
Open the particle system in cascade and enabled “set fixed bounds”. The default bounds should be okay but if not just try increasing the relative bounds size.
Let me know if that helps,
Ed
