Describe the bug
Problem using copy-paste feature of gameobject with UI Particle component on it, constant null reference exceptions starts to appear - need to remove UI Particle component and destroy all UIParticleRenderer gameobjects and setup again in order to fix issue.

UPD: Problem appear when clicking on any UIParticleRenderer gameobject even after destroying them and UIParticle component and attach it back.
Log of error:
