My simulation runs at 1 FPS and I noticed my console is spammed by "missing cache error".
If I opened my blend file : everything's OK.
If I edit a mesh (enter and exit edit mode with no change) : 1 FPS and missing cache error spam
If I stop then run the simulation again : everything's ok
This is very annoying I have no idea why there is such error and why it's solves itselft by reloading the file / retarting the simulation.
I'm using blender 2.79b. Blend file is under licensed so I can't share it... I'm testing simple soft body collisions.
