I can't get my Packaged Project to keep Child Blueprint Actors

K so i’m pretty freaked out right now because most of my game runs and uses These child blueprints.
I know i’ve seen this posted before but i didn’t think there was a clear answer. If you like i could post up screen shots of my game.
-I’m using Unreal 4.7
-I’m using child blueprints for my weapons such as shot gun and pistol
-Every time a restart the editor It wipes the selection out
-In cooked projects it also doesn’t work.
-I’ve tryed saving it. Does anyone know how to solve this issue?
