Wish for unique unit not working

[vfb]

I set up a test game. Two nations cast Wish on the same turn, both wishing for "King of Magma", wishing by name ("Rhuax") was not allowed.

One nation got just one message:


Arriod has cast Wish.
Suddenly a King of Magma appeared in the Laboratory.


The other nation got two messages:

Wonde has cast Wish.
Suddenly a King of Magma appeared in the Laboratory.


followed by


Suddenly the King of Magma disappeared in a puff of smoke.


But ... he's nowhere to be found! He's not in either nation, and he didn't attack either nation.

Edit Whoops! I forgot that the unit shows up as a non-commander, when it doesn't exist in the game yet.

Maybe Rhuax was magically killed in the same turn? So, he shows up outside the gates, and gets hit with a Mind Hunt (targeted at your capital), so no battle took place? Or if he was horror marked, maybe he showed up, and got killed by a horror before he could fight your militia.
