Hi Tom - Indeed, when combining the elements the new version makes sure 
  that all the candidate views have the same number of time steps. But 
we should propbably bypass this test if the view is empty (like we used 
to in 1.65).

I will change this in the next version. In the meantime, you can just 
run "View->Remove Empty Views" ("Delete Empty Views;" in a script) 
before attempting to combine the data.

Thanks for the feedback,
