vcs.download_sample_data_files() keeps on downloading th_yr.nc

[jypeter]

@doutriaux1 I wonder if there is a problem with a) vcs.download_sample_data_files() or with b) th_yr.nc

When I execute a) in a CDAT version where it has already been executed, it apparently sees that the files are already here, except for b) that it downloads 3 times. Same thing if I re-execute a)
