Hi jstack,
Thanks for using out plugins.
The only thing that I can think of that affects urls is the WordPress autosave. Sometimes if that saves without there being a title it changes the url to all numbers for the id.
We do not have anything that would change the url to remove the title in the admin, it could be some javascript doing it as well, but it is hard to say where that would be coming from.
Does it do it often or was it only for one event?
Does that help?
