NullReferenceException when trying to save

[agiro8747]

Greetings,
I'm trying out your engine but when trying to save my scene I get a NullReferenceException.

Here's the message:

Error: There was a problem saving the solution. System.NullReferenceException: object reference is not set to an instance of the object.
on the following place: SiliconStudio.Assets.AssetItemExtensions.GetProjectInclude(AssetItem assetItem) place: C:\TeamCity\work\80a49494ba341a6a\sources\assets\SiliconStudio.Assets\AssetItemExtensions.cs, line: 19

I tried my best to give a decent translation to English as my system is in Hungarian, but you probably wouldn't understand that gibberish.
Your engine looks quite promising. Please correct the issue if you have the time.

edit: btw your website contact form crashed as well when trying to reach you that way :D pls correct that as well.

This usually means that at least one object in your scene is messed up. Load the project again and see if there are any errors or warnings (red and yellow text).

Yup, that indeed solved it. Thanks for the assist!
