Short description of error
Baking a particle system with Disk Cache checked and Cache Step set to greater than 1 results in the baking failing.
No error is reported, but the bake is obviously corrupt.
It worked in 2.79.

Exact steps for others to reproduce the error

  1. Extract the archive and open the .blend file. (in 2.80)
  2. Playback works at this point. (Particles fall down from the plane.)
  3. Click Delete Cache and then Bake.
  4. Try playback again. It's not incorrect. (Particles appear at the bottom and don't move. If you check the cache folder, you will see it cached every second frame---instead of every 10th as configured, except for the first step.)
