Doesn't need additional description :)
Everyone knows this error : unable... : previously freed instance on a null instance.
Is there a way for checking if a node in array ceased to exist, in a way not provoking this error ? Checking Insidescenetree and if = null won't work.

Yes. You can use is_instance_valid(). For example, this

var test = TestClass.new()

print(is_instance_valid(test))
test.free()
print(is_instance_valid(test))

will print "True" then "False".
