I don't know why but it overwrites the description every time you issue a patch, which means you'll need to take your description and copy/paste it into a notepad or word file. Then paste it back in after a patch.

I've done that for all four campaigns I've got out, unfortunately. Its a pain. That and tags not working could have used a fix.

Thanks for the info Artyoan. Unfortunately, I only discovered this three days after patching.
