Using this plugin makes the text of my posts disappear

Hi there,

I’ve been searching the reason for a while, and found out that this plugin makes the text of some of my posts disappear. This posts are imports of various old sites of mine, imported using the import functions for Blogger and MovableType. All is fine, but when NT Redirect is active, only the title is shown, the rest is gone. And not all posts have troubles, only some. I can’t understand why. Has someone else reported this yet, and can you think of an solution?

Thanks in advance,
Marcotics
