What is your nastiest surprise ever in Dom III?

Seems pretty tame compared to these, but:

I have a mage with boots of the planes (teleport) and the Chalice. He teleports around to different armies and reduces afflictions. This is necessary as all my mages are ancient and keep getting more and more afflictions, and mages are the basis of my armies.

Anyways, one turn he just disappears. Can't find him. Overview doesn't list him. Can't remake the chalice or the boots, so I am pretty sure he is out there somewhere. No idea what is going on. Except my extended armies are falling apart, and my mass of researchers/caster in the capital are dying off quickly now.

Lost in Space and Time, perhaps?
