When doing a copy, the type= $_GET field is blank instead of showing the content type alias.
Also, some fields aren't copied over for some reason when others are. I don't know if it has to do with where they're stored or what.
To replicate:
1. Check boxes of items you want copied.
2. Click batch and setup your copy command.
3. Click copy and open the newly copied article.
4. It will give a message "Oops! Content Type not found.. ; ("
I can fix this manually by putting something in the type= field, but this is not going to work for myself or other people editing the site.
Example:
http://SITE_URL/administrator/index.php?option=com_cck&view=form&return_o=content&type=&id=295
instead of
http://SITE_URL/administrator/index.php?option=com_cck&view=form&return_o=content&type=product&id=295
