System Information
OS: Windows 10
GPU: Gtx 970

Blender Version
Broken: 2.80 1af810b4ff 2019-02-20

Short description of error
Cube metaball are broken in multiple ways (other metaball are fine):

  • Their selection ring isn't visible
  • Weird behavior when deleted and added

Exact steps for others to reproduce the error

  • Default startup
  • Add a cube metaball
  • Duplicate it with Shift+D
  • move it next to the first metacube
  • Delete one of the metacube
  • Both disappear and only a selection ring remains

Additionnal note : to see the meta cube again you need to readd another

Quick video to illustrate the problem: GZBsC7ueFS.gif

This also happens with the other metaballs.

You just have to delete the first one you added and the others will vanish.

This is a limitation of the current implementation where the first Meta balls is the parent of the group. The group is determined by the object name. A better solution would be to have a proper group or use the collection system. But not considered a bug.
