Please explain your issue is in as much detail as possible.
I am playing as the Emperor of England and King-Bishop of the Scotland resides in Isle of Man. He has the following titles: Theocracy of Scotland, Prince Bishopric of Isle of Man, and Bishopric of Auchterarder. Since he already has one duchy title I cannot give him the Duchy of Isle of Man. I have tried to give this title to my other vassal kings but they all usurp it right after. So thanks to this glitch I can continously gain 200 prestige for each 161 gold and keep my other vicekings at 100 happiness.

Steps to reproduce the issue.

Do you mean "destroy" rather than "usurp"? If so, I think I've seen similar behavior, though I hadn't thought about exploiting it for prestige and opinion.

Yes. I meant "destroy". It ended once I gave the title to a duke.
