Description

System Information
Operating system: MacOS 10.14.2
Graphics card: AMD Vega64

Blender Version
Broken: 2.80, 1b6a394d862, blender2.8, 2018-12-03

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.
See screenshot.

Thank you!

If I bake, it works as expected. However it seems like if you just use the automatic playback cache, this issue happens.

@Brecht Van Lommel (brecht) who is in charge of the physics cache stuff?

Generally you have to bake any physics systems before rendering. However it seems 2.79 was more forgiving in this regard, still failing in some cases but working most of the time.

Re-opening, things are a bit more fragile here, and needs a closer look.
