Why is the constructor function for a custom class getting called multiple times?

The problem you have here isn't coming from your code, but from the timeline. The code from your class can only access the elements of the current displayed frame, and loose access to the others instances, symboles, anything which is outside the current frame.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
