Unity Crash on Input(SOLVED)

Hi,

I'm currently working on a project for a Mastery/Skill tree system.
When i hit the play button everything works fine until you give an input to Unity, which is required for the "game" to do what it's supposed to do. It crashes unity. This happens with both mouse and keyboard input but only when it has a programmed function. Is there an error in my code or is it related to the mac version of Unity?

I'm not very good with C# yet and this is the first project if worked out myself, and i know this is not the most efficient way of doing it.

Below is the code i'm using:

Mastery_Manager Classe:

1. using UnityEngine;
2. using System.Collections;
3. using System.Collections.Generic;

5. public class Mastery_Manager : MonoBehaviour

23.         Defender.IconAvailable = defenderIconAvailable;
24.         Defender.IconNotAvailable = defenderIconNotAvailable;
25.         Masteries.Add(Defender);
26.  
27.  
28.         foreach (IMastery mastery in Masteries) {

I'm not sure if this is what's causing the problems, but I imagine they are or will cause some:

mastery.Start();
mastery.Update();

Both Start() and Update() are built in and run automatically which means whatever is in the Masteries script Start() gets run when the script first loads and everything in the Update() will get called every frame regardless of your foreach loop.

 

I do not think that is true 'cause the script doesn't inherit from MonoBehaviour and isn't attached to a gameobject.

 

Okay so i have found the problem: There is a Stack Overflow Exception thrown at the set from Available. I'm not really expierenced with c# so i do not know why this exception is thrown here.
Anyone who could help me out?

EDIT: Was looking at the code and found it: I spelled available = value with a capital A reffering it back to the property causing the stack overflow.
