GetInstanceTransitionTimeElapsed doesn't use TransitionIndex.


float UAnimInstance::GetInstanceTransitionTimeElapsed(int32 MachineIndex, int32 TransitionIndex)
   // Just an alias for readability in the anim graph return  

float UAnimInstance::GetInstanceCurrentStateElapsedTime(int32 MachineIndex)
   return GetProxyOnAnyThread<FAnimInstanceProxy>().GetInstanceCurrentStateElapsedTime(MachineIndex);

So, if Animation BP run few few transitions  at the same time, GetInstanceTransitionTimeElapsed will not return right value. It will ignores the location of the Transition and returns the latest value transition's value. This is misleading.


As far as the past update history is seen, it is probably due to omission from the target of batch replacement.


Steps to Reproduce

Use GetInstanceTransitionTimeElapse in a transition rule
