I spoke to KamenGrappler in early April and he was still waiting for a reply from Oki while Oki was waiting for a reply from him. Seems like the message didn't go through and both were just waiting for the other to reply. I'm pretty sure that was the reason for the huge delay.
Oki still had the memories at that point and because I notified them both, that deadlock finally ended. Since I have stuff with Oki anyways, I asked that he include my memories with my stuff shipping from Japan. But I'm sure those memories should've already been shipped out to KamenGrappler by now unless they've been caught up in another one of those message reply deadlocks.
