You're definitely More Awesome Than Me, but you knew this already. Thanks for the update!

I used to play with harderjobs before I installed Pets. I no longer have this hack in my game.
Before posting here, I made a quick search on the Sims 2 BBS - looks like I'm not the only one experiencing it.

http://bbs.thesims2.ea.com/community/bbs/messages.php?threadID=0f41ec95be485f9598be749466d93eea&directoryID=108&startRow=101&openItemID=item.108,root.1,item.43,item.104,item.127,item.23

Since this hack is related to Job Fixes, I thought I could submit my problem here:

When a Sim calls a pet's employer to retire, the calling Sim's own carreer falls down back to a low-level job!

If this isn't a bug, I don't know what to call it...
