Constant crash on mobile device when using construction script in BP

I followed the endless runner tutorial in an attempt to turn it into a mobile game. The tutorial uses the construction script to make the random course generator. When I packaged it for development, the game would open, but the course generator was not working properly. It would only spawn two of the ten course pieces it was instructed to spawn. I thought this may have been because it was in development build, so I packaged again as a shipping build. Upon installing and launching on my mobile device, it crashes every time after the splash screen. Is there a known bug with using the construction script for mobile? Is there a work around?
