UI Prefab not instantiating on build for Android.
I made a UI list instantiate for weapon upgrades. It works fine when running it in the editor but when I build it and try to run it in Android nothing pops up. While looking up what happens in logcat this error pops up:
I/Unity: NullReferenceException: Object reference not set to an instance of an object at CreateScrollList.PopulateList () [0x00000] in :0 at CreateScrollList.Start () [0x00000] in :0 (Filename: Line: -1)
What doesn't Make sense to me is that this if the object wasn't set to a reference wouldn't I get an error in the editor?
Here is what the scripts look like:

This is how it looks in the editor: 
This is show it looks in android build: 
Any ideas? I'm really not sure what I'm doing wrong here.....

After alot of debugging I narrowed the problem to my weaponInfo class. I had turned my weaponInfo class into an asset that inherited from mono behavior. Once I deleted this and created my WeaponInfo class through constructors. Everything worked like normal when I built it. Not sure the specifics of why this worked so if someone can elaborate that would be greatly appreciated.
