I've test my game in Unity Editor, after that a few seconds memory run out. *1. I just pressed play in editor and wait 30 seconds - 60 seconds It's does bug. *2. Now I try to not waiting but playing still had memory bug when instantiate gameobject. Unity 5.4.0b1 is fine because I was doing my work along this week with Unity 5.4.0b1. Thanks!
