Decouple

[Silviu250]

Hello! Some of my rockets have an annoying bug. When I decouple a stage, camera focus is on debris, but that's not a problem until I switch the stage and my ship does not work properly. In tracking station it is a new ship and when I 0ress "space" to turn Engines on, they decouple. Help me!

Sounds like you're not placing probe cores or command pods properly, and you're not setting up your staging.  You need to tell the game what activates in what order. 

Can you post a picture of your rocket in the VAB?

Two KSP facts:

1) The camera always follows the center of mass of the active ship. The part you place first in the VAB is the "root" of the ship, and as you decouple various stages the active ship stays with the designated root. You can use the Re-Root tool in the VAB to change the root part; in most cases you'll want the root to be the Pod part on the upper-most stage.

2) KSP will mark a craft as "Debris" if it does not have a Pod on it.

Therefore, if you decouple and the camera stays with the section marked "Debris", it is because a) the designated root part was on that half of the craft, and b) that half of the craft has no Pod.
