Question Runtime Animator Controller Override resets animator variables ?

Hi guys,

In 2019.3 i was overriding Runtime Animator controller and everything was smooth, for instance ;

Code (CSharp):

1.  
2.         animator.SetBool("AutoTrigger", true);
3.  
4.         // Override Animator if any
5.         if (_AnimatorOverride != null)
6.             animator.runtimeAnimatorController = _AnimatorOverride;
7.         else
8.             animator.runtimeAnimatorController = SavedState.Controller;

Was running smoothly, i would then trigger whatever animation state i needed and it would pick up AutoTrigger value just fine.

Now in 2020.1, when assigning a new runtimeAnimatorController, AutoTrigger just resets to False.

Is this a new intended behavior ? Is there a way to avoid that ?
Ofc In the example i don't really care, i just set up AutoTrigger after assigning Runtime Animator Controller and it worked, however this is very problematic for all other animator variables not linked to this system.

Thanks in advance
