It does for me.

First of all, I suspect that maybe you are not running the version of  
Org-mode you think you are.
What does M-x org-version return?

Second, you can try to recreate the file that links IDs to files.   
Just load
all the relevant Org files into Emacs and then run

M-x org-id-update-id-locations RET


Does this help?
