Hi.
From the error it gave i can see that the key was not found.
(2nd line "KeyNotFoundException")
Does the 'test' variable have a value?
and is it the same on the 'ES3 ArrayList Save' ?
The test variable must have a value and be the same for save and load, this is used to reference the save .
On the bottom left of the image below you can see a check box called 'Debug'
you can 'Check' that to see the values from your variables inside your actions
