Description

On a complicated aviary model, list_pre_post at the command line gave me no pre or post systems. If I ran prob.list_pre_post, I got the reasonable and expected pre and post systems. I think that means the internals are working, but the command line tool has some issue.

Example

I have a model that reproduces this, though it is a complicated aviary model.
