Elm won't notice Togepi hatched.

[Superkid11]

In my new HG run, Professor Elm won't notice that the togepi egg hatched. I call him and he just says to call him if anything changes. I visit him and he says the same thing, even if Togepi is the first in the party.

Probably worth noting that I pokesav'd the thing before it hatched. But I didn't touch the hidden hex, and I was sure to roll a new PID. What's the deal?
