Spawning a character using an existing character as a template causes the spawned character to inherit the animation of the original and may lead to a crash.
This appears to be unique to character classes, and may be linked to CharacterMovementComponent, as spawning other AActor types does not cause this crash.
Newly spawned actor has the exact animation as the TPC and no new input can be read. Triggering Keyboard event a second time causes the editor to crash
There's no existing public thread on this issue, so head over toAnswerHub just mention UE-45206 in the post.
