Can anyone explain this bug?

Inside the attached .rar
Two seperate objects are made, object A and object B, but they share the same variable (only works with arrays) even though they aren’t linked in any way. Any changes made to A is reflected in B, and vise versa.

How would I go about fixing this issue? (SIMPLY, aka I don’t want to write a class or whatever, I just want to know if I am doing something wrong, like not writing new or something) :look:

The attached movie clip creates a corresponding object. :b:
