Error: Particle collisions will be not rendered.
Steps to reproduce:
Created a plane as floor, activated collisions
Created a plane as emitter, activated collisions
Created a Icosphere, used it as particle object
In 3D Viewport everything looks as expected, particles hit floor.
When the exact frame is rendered (no matter Eevee or Cycles) the particles fly through the floor.
