No, I am advising you to check whether your unobserved 
variable shows the behaviour I described when you use the 
non-parametric one. Probably the easiest way is to simulate
the unobserved variable and observe the distribution of the
survivors over time. Moreover, that pattern seems less 
likely to occur when you use more mass points, so adding
a mass point would be a straightforward sollution when
you encounter this problem.

Hope this helps,
Maarten
