O.K. That's good to know.

No, it doesn't, that's what has me stumped. It should be returning a
contiguous array (because of the .astype method).
So, figuring out why the .astype() method is not returning a contiguous
array is the key to understanding this, I think.
If you could determine what the parameters being passed to the .astype()
method are and try to reproduce the problem of not getting a contiguous
parameter on output, that would be very helpful.
Sorry for your trouble.
