FileNotFoundException on Create SiteCollection based on Custom Site Definition

Hey guys,

Today i gonna try to renew our SiteDefinition project. First of all i try to save a site collection as template and importing it into Visual Studio.

Importing in Visual Studio was not the problem, but when I redeploy the solution and try to create a new site based on the newly created site definition I got the error

So I gonna take a look at the ULS Log and find the following:

"The system cannot find the file specified. "

So I start researching why this won't work. 

Like below shown the Folder "Other imported Files"  was missing in the newly imported Site Definition Project.

Here are the steps how I resolve this problem:

• Login to the Site Collection as SiteCollection Admin which you want to save as template
• Go to SiteSettings
• SiteCollectionAdministration
• Site Collection Features
• Deactivate the Feature "SharePoint Server Publishing Infrastructure"
• Reactivate the Feature
• In my case I have to try it 2 times to reactivate the feature.

After that I save the site as template, and import it into visual studio and everything has been fine.

I even doesn't know why the hell this has been corrupt, The only thing we have done was to backup the site and restore it on a new WebApplication.

I would be very grateful for any answer why this going to be happened.  

Cheers
