An Alternative Solution

if (HasAuthority())
	//                    B                            -         A
	//             -----------------------------------   -----------------
	// Direction = TargetLocation + GetActorLocation() - GetActorLocation()
	FVector Direction = TargetLocation.GetSafeNormal();
	FVector DistanceOffset = Direction * Speed * DeltaSeconds;
	SetActorLocation(GetActorLocation() + DistanceOffset);

TargetLocation is in local space (relative to the moving platform). To move it into world space we can add the moving platform’s location.

But since we’re calculating B - A for direction, the + GetActorLocation() and - GetActorLocation() cancel out, and we can simply use a normalized TargetLocation as our local space direction.

Scale it by speed and delta time and add it to GetActorLocation() to get the result.

Excellent work. Thank you for taking the time to share this with others.

Yes, I came to the same conclusion that you just needed to add the normalized TargetLocation but scaled to get the usual frame interval vector.
