Scene loads differently when loaded from another scene than selecting that scene first, in the editor. [answered]
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
Waiting for a while to see if it is just taking time to load (1 min +), in comparison to the ten seconds when it loads on its own.
Built it and seen if the problem repeats itself or not, allowing me to decide if it is due to the editor, like when you switch scene and the lighting goes dark. However, the problem repeats itself.
Upgraded my Unity to version 5.3.4f1, then used SceneManager.LoadScene() instead of Application.LoadLevel(). No change evident at all.
What I think may causing it
Reading many web pages i understand that Unity's scene loading and scene system can be annoying
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).

The Console Messages
When the scene is loaded directly
When the scene is loaded from another scene
Asked this question on stack overflow and got a response, what i was doing wrong was that the code which was not read as shown by the lack of debugs, was where if (Time.frameCount == 1). I used this function to ensure this code happened after my start function but of course when i opened it from another scene the Time.frameCount had already been going so that code was not completed and i only got a bit of my desired results. To solve this in my scene i will get the frame count in the start function and then in the update function i will say do --- when the frame count has gone up by one.
Hope this helps anyone who goes through a similar problem.
If it's ok for you, you could describe what kind of objects are in the scene and what they do... Like are there any objects in the scene that could cause problems at runtime?
Thanks for your reply, I've added further detail into the original question, if you require any more just ask
