Demilich not reporting for duty

[Tellus]

Here is my problem. I cast Lichcraft and the next turn my demilich didn't show up. In my messages it says "Raitor has cast Lichcraft." I am positive the demilich is not in the province to which he should have been summoned. There were no battles there and no events affecting that province either. I scanned through the nation overview and couldn't find him anywhere.

If someone could point out how I'm being stupid (as I'm sure I am), I would appreciate it.

Thanks
