yeah but where do you cast to as pale and make it a reference, begin play?
If so what is happening is that your AsPale reference is referencing the first instance (which works) but then when you try to do the same thing for the second instance (you are still only referencing the first instance, so it fails, returning that the reference is invalid because you already destroyed it)
A quick solution is to set whichever instance you interact with as the AsPale Variable as your first action wherever your code to interact is
