sitecore installation wizard could not install some content <p>I would like to ask you if someone has similar problem. I am using Sitecore.NET 7.2 (rev. 151021) with Solr. I need to add some items from prod to my local sitecore instance. When I create package and tried to install specific content I get exception null reference exception. It doesnt depend on the content. I tried to used package designer with varios content and always I get this exception.</p> <p><a href="https://i.stack.imgur.com/pXvvo.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/pXvvo.png" alt="enter image description here"></a></p>
