Reproduction steps:
1. Open the provided project "case_1223207-steel-flood.zip"
2. Enter Play Mode
3. Press "ESC" -> "Quit to menu" -> "Start" -> Select a load slot

Expected result: GameObjects with Animators are not made invalid when instantiated via Addressables after a Scene reload
Actual result: GameObjects with Animators become not valid thus disabling the Animations when instantiated via Addressables after a Scene reload

Reproduces on: Addressables 1.3.3 (2019.3.4f1), Addressables 1.6.2 (2020.1.0b1, 2020.2.0a2)
Does not reproduce on: Addressables 1.2.4 (2019.3.4f1), Addressables 1.2.4 (2020.1.0b1, 2020.2.0a2)
Could not test on 2018.4.18f1 due to package errors in the Console

Notes:
-The issue does not reproduce in Build
-Making a New Addressables Build does not solve the issue
-Error message printed in the Console window:

The Animator Controller (FirstEnemy) you have used is not valid. Animations will not play
