Kit 105 and particle cloth for hair physics - various strange behavior

I was trying out USD Composer (Kit 105) with particle cloth for getting some hair bounce. Someone was asking what I did, so I did a rough recording of what I did. A number of things went wrong (hair jumps to wrong position, OV crashes, etc). Some success, but sharing the video in case useful to look into the various problems that occurred.

Examples of problems:

  • Colliders would disappear after a while for no apparent reason
  • Unable to add a sphere collider
  • Unable to get attachements (hair roots) to the sphere
  • Mesh would often jump to different positions (e.g. the ground) unpredictably
  • Crashed once (locked up)

Note: I reported some of these in the past - this is just an update for 105.
