I'm running into an odd problem with Visual Studio 2013 (Update 3) and SharePoint 2013. I created a Sandboxed solution for SharePoint 2013. I then right-clicked on the solution 7 times and selected to add a new List each time. VS created a new feature for each list. I deleted all but the first feature and added each list to that feature, so the end result was 1 feature with 7 list definitions and 7 list instances.
Builds and deploys just fine.
I then closed the solution and opened it again. VS created 6 new features and put 1 list definition and list instance in each feature. Is there a way for me to put all of my list definitions and instances into a single feature?
