List <int> instance = x; 

This doesn't create a copy of the x list, it just creates a pointer to that data. It means that when you call instance.RemoveAt(i), you actually remove data from the x list. When you do that, the whole For Loop logic basically brakes. This is how you should create a copy of the list : http://stackoverflow.com/a/1952191

And if you wanna remove items while iterating through the loop, just go reverse:

for(int i = x.Count-1; i>=0; i--)

{

// do stuff

x.RemoveAt(i);

}
