I don't think its a glitch. Or maybe it is. Who cares, it worked for me and I'd like to see if people can duplicate this in v1.1.
Playing as the Italian faction, I took over Rome and the Papal States (unknown to me the Pope would make his return shortly). In my gave save it was the year 1140 and he would come back 1143 or 1145.
Since, despite all my attempts I couldn't stop him in battle, I got angry and razed the Papal States to the ground; destroyed all the buildings and only had one unit on the map, the duke or governor (whatever the title).
In Rome I have armed forces, a castle, all that (I don't know if forces in Rome affect it or not).
But after I did this, the years past. Now its around year 60 or so and he never came back. Maybe he doesn't want to go into a destroyed territory with no place to live (no castles or fort to hide in).
In any case, the land makes 157 monies a year, and that pays for the unit on it and more so, I'm making out. Plus no pope screaming at me that I'm raping France.
