 I guess I will get bitten  by the most obscure WordPress bugs ever. I'm
 also prone to try something stupid. :P

 I've set up a WordPress MS site at http://funroe.net running in sub-
 directory mode. For some reason menus do not work on sub-directory MS site
 at http://funroe.net/projects. Every time you make a menu and save the the
 term_id would become 0. This causes all menus to break completely.

 Of course I suspected some database corruption since this site is old and
 a WPMU convert that has been running of trunk for a while. To clean it out
 as much as I could I even did an WordPress export and import to another
 site running in a subdirectory at http://work.funroe.net/wpmu_t/converter/
 the WP MS root is at http://work.funroe.net/wpmu_t/. Menus work as
 expected.

 Converted and moved the DB tables back to the Main site at
 http://funroe.net/projects and the menus will revert to term_id 0 on save.
 The DB autoindex looks good and initial creation seems fine, but something
 tricks the custom taxonomy to go to 0.

 This seems to only occur on a domain using multisite sub-directory mode on
 the root directory. WordPress multisite in sub-directory mode in a sub-
 directory seems to work fine. This is the case for all sub-sites even new
 ones.

 I'm going to try to test this issue on a fresh install of a root domain
 somewhere as soon as I get time.
