[DAS2] Problems with biopackages DAS2 server

I'm having some problems with feature responses from the DAS/2 server at
das.biopackages.net.  It looks like in the das2feature XML at least some
features are now pointing to themselves as parents.  For example, as
part of response to
<FEATURE id="feature/U75330" type="type/SO:mRNA" name="U75330">
    <PARENT id="feature/U75330"/>
    <LOC pos="region/chr21/21292691:21834284:1"/>
Another problem I'm seeing is server internal errors in response to
combination of an overlaps and inside feature filter, for example:
returns an HTTP status code of 500, "Internal Server Error".
Has the combination of overlaps/inside filter not been implemented yet?
Or is this possibly because of the size of the inside filter's region?
I haven't noticed either of these problems before, but for the last
several weeks I've only been testing the higher-level responses
(sources, regions, types) while redoing the client GUI, so I'm not sure
when this started happening.
