In puzzle 2059, create one or more bands.

Enter ligand design mode. Make a change to the ligand, such as adding or deleting an atom.

The bands disappear.

Getting the bands back requires three undo commands (control-z or Undo button). The undo graph seems to show two extra steps.

The multiple undos with the ligand design puzzles is a known issue. There should be a fix to it coming out with the next devprev release.

Bands disappearing when you modify the ligand is also something which is not unexpected. Keeping track of which atom is which when the molecule changes (to figure out where to put the bands) is somewhat tricky. We haven't quite figured out how to robustly match things up in the general case, so just clearing the bands to the ligand is the (temporary) "safe" option.
