How to reproduce:
1. Open attached project
2. In Editor open any Scene (e.g. Assets/Scenes/GameScene)
3. Create any object in Hierarchy (e.g. Cube)
4. Create empty script on new Cube object
5. Open created script
6. In script declare variable with some value:
Example:
{code:java}
private int testVariable = 99;
{code}
7. In Start method print out variable:
Example:
{code:java}
void Start()
{
Debug.Log(testVariable);
}
{code}
8. In Editor enter Play mode and check Console for the printed value
9. Exit Play mode
10. Go back to the script and change value to something else
Example:
{code:java}
private int testVariable = 55;
{code}
11. Wait for recompile to complete
12. In Editor enter Play mode and check Console for the printed value
13. Exit Play mode
14. In Editor Enter play mode again and check Console for the value

Expected results: Variable value printed in console matches the one in the script when entering Play mode for first time.

Actual results: Old variable value is printed when entering Play mode the first time. It is only updated after entering Play mode the second time.
