Please help

,Hi!
I’m working on a game with randomly instantiated rooms from prefabs. Sometimes, and not always (The pictures are 7-8th. try) the camera wouldn’t record the room. it is there and I can stand on it and i can see it in the scene window but its nothing on the camera.

Please help!][1]
