Screen wrap code works for player but not all instantiated gameobjects.

I am making myself a very simple game as my first project in Unity and everything in the game is supposed to wrap from left to right and top to bottom (and vice versa). I am using the same code to wrap game objects for both the player and the baddy objects, but while the player wraps, only first and second generation baddies wrap.

To give a little background, the game starts with the player and one baddie. When the baddie is hit, it is destroyed and two more baddies are spawned. The initial baddie and the two baddies from the split WILL screen wrap. Any baddies beyond those two generations will NOT screen wrap.

Edit: I have just noticed the third generation + baddies also don't rotate. It looks as though for some reason after the second generation the baddies stop using the Update function.

Edit 2: On testing it again this morning it's not wrapping or rotating any of the baddie objects except the very first one. So none of the baddies instantiated as a result of a split are updating. I'm hugely confused. The edit I made yesterday was not incorrect. I tested it multiple times before making the edit.
