Hello!
I have some capsules as my AI at the moment and everything was working fine untill i opened my unity project again. The gameobjects (Capsules) dont appear in the game view anymore but they are visible in the scene view. Thay have a weapon attached to themselves so when they fire, only the muzzle flash is visible. But if i change scene to my main menu scene and drop an AI infront of the camera there it´s visible in both game and scene view. So the problem lies with just that scene.
