Short description of error
Baking a particle system seems to have broken somewhere along the way while making this blend file. It was working earlier but recently stopped baking correctly. However, when I play the animation without a bake it looks correct. Once it is baked it only bakes the last few seconds and the particles don't come from the correct source.

Below, it is playing with correct looking particles

Below, is after all dynamics have been baked. But it only really bakes the last few seconds.

Exact steps for others to reproduce the error

  1. Setup a particle system
  2. Bake all dynamics
  3. Free All Bakes
  4. Bake all dynamics

It also doesn't work if I try to just "Bake". Only the last few frames are baked.

I can't reproduce this, so I'll assume this has been resolved.
