I have a custom plugin that saves meta data using a bind the the save function, which puts event times and dates into a seperate table. This works absolutely fine, except if the user leaves the edit page open and (i assume) an auto-save occurs.
This then (even tho the details are still in the correct fields) saves some incorrect and unusable string into the table. It still saves the correct post_id and blog_id, but the custom meta boxes values are not saved properly and are essentially deleted.
Secondly, at seemingly random occasions, the header image (the custom one that a user can add) just disappears. I can't give anymore information than that because it happens so infrequently and I cant seem to reproduce it!
