Quite a simple problem really, but after searching the internet i am struggling to find an answer.
Problem
Scene doesn't load fully, some parts work, some don't, from another scene (through Application.LoadLevel() ), whereas opening the scene directly and then playing it works fine.
What I've tried
What I think may causing it
Thank you for reading this, I hope it is a simple problem but to a quite inexperienced Unity user (ME) it is quite perplexing. If any exact details are required i will add them on but to me they are unnecessary (and take a lot of effort too).
Further Detail (If you need it)

The Console Messages
When the scene is loaded directly
But interestingly when it is loaded from another scene it does not have any debugs of "2HEY" or "3HEY".
Time.frameCount is counting frames from the start of the game. So if you load the scene from another scene Time.frameCount will be greater than 0 for sure.
Also it's faster to debug your game instead of using logs to see what's going on. Just hit Play in MonoDevelop and (for Unity 4.3 and below) choose Unity Debugger, place breakpoints where you need to stop and check variable values, then hit Play in Unity.
Good luck
