jtost on "[Plugin: Remove slug from custom post type] Need to refresh permalinks after adding a new post (custom post) to avoid 404"

Hi!

First of all, thanks for your plugin. I'm experienced following behaviour, that I think is an error:

When I add a new post/page of a custom post type and when I try to view it I get a 404 error. To avoid this, I have to go to "Settings / Permalinks" and update the page.

How can I avoid this problem? I tried to flush the rewrite rules after the post save but without luck.

Thanks for your help!
