struggling with packaged game issues. Tried to blueprint for coop game and it’s working in editor but not in packaged game. Need to add lot of print strings to figure this out 
So my game will have less features. Guys - package your game and check if everything is working as intended.
Hope this is fixed in 4.9 really frustrating now
