Certain codepaths in USkeletalMeshComponent::InitializeAnimScriptInstance can cause linked anim graphs that are running in Post Process anim bps to be unlinked. The problem only occurs when the linked graphs are set via the BeginPlay event in the post process anim graph.
This is because it's possible for InitializeAnimScriptInstance to initialize the post process anim instance before it initializes the main anim instance. But when the main anim instance is initialized, all linked graphs (including those linked via a post process anim instance) are cleared.
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-234750 in the post.
