I’m using Widgets for the first time to create a main menu, host menu, join menu, etc., and it works perfectly. However the only problem is that once the widget is removed and it transfers me to the actual level, my player can not turn unless I’m holding the left or right mouse buttons down. I’ve looked all around and it seems that no one else has had this problem. Nothing has changed the mouse in the Widget blueprints besides showing the mouse cursor. Help would be greatly appreciated. 
I just figured out the problem. In the Main Menu level, I had used the Set Input Mode Game and UI node, and when switched to the actual game level, I hadn’t made it Set Input Game Only.
