Make Links -> Object to scene

Using 2.58

I’ve got 3 objects selected and when I go to ‘Object’ -> ‘Make Links’ -> ‘Object to scene’, all get linked across in the ‘Outliner’ viewport. However one object is missing in the 3d view and everywhere else…

Originally this object was set as ‘Invisible’ in the Physics tab, but i’ve tried it without.

I’m following along to this (having started in pt 1):

If I make a whole new scene using ‘Link Objects’ it get copied across properly…

Any ideas?

Technically it’s a mesh and another mesh copies properly, so it shouldn’t be a bug (?), so it probably depends upon some property or other…
