Please explain the issue you experienced in the most condensed way possible
I declared a Holy War against the Almohad Caliph and rather than granting me his titles, it simply vassalised him. When I try to revoke his land, it says, "XXX cannot be revoked from YYY as it would make him hold only Titles with no land." When I try to revoke his Almohadi Caliphate title, it says, "Almohadi Caliphate does not control a Faith." As a result, I cannot take his land and cannot get rid of him.

Please explain how to reproduce the issue
I'm guessing, but create a head of faith title and then convert every territory of that faith.

Is there anything else you think could help us identify/replicate the issue?
Likely happens a bit in North Africa.

I have attached a save game
Yes

Muslims vassalise holy war victims normally, get him to convert then strip his lands, might be a cover to stop Coptix popes getting land stolen tho

I couldn't ask him to convert as he was a head of faith. The solution was to release him as an independent vassal, wait 10 years and conquer the land normally.
