Logic is not working in package

In my blueprint script, I am spawning static meshes on bone locations of a Skeletal mesh when the animation finishes. In another script picking up static mesh and placing on certain locations sequentially like a assembly.
Every thing is working perfectly when I play it from my project. However as soon as I make build/Package of it, spawning behavior gets changed and meshes start to spawn on totally different location and sequence of the assembly gets stuck.
I have tried all the settings for packaging the build Dev/Shipping/Client Shipping but no change.
Please Help.
