Parent/Children links in RT 3.6.6

Has anyone else experienced the issue where the fields for links on the
homepage are no longer populated in 3.6.6? I recently upgraded an install
from 3.6.5 to 3.6.6, and now those tickets which had parents or children no
longer appear to reference them. If I look at 3.6.5, the links show up, so
they are still in the database. Any ideas on how to begin troubleshooting
this?

Thanks,
