Just a minor thing, I noticed this event firing 3-4 times within ~a century in my current game. Different Beit Dejans in different provinces all over (teutonic) KoJ, owned by different Holy Orders.
No mods, just regular CK2 with everything but Sunset active.
Save game is here: http://s000.tinyupload.com/index.php?file_id=01725635746257363108
(I hope it's not a concern that it's an unfinished ironman... I also hope the link is okay, I did not quite figure out how the "Upload File" button to the bottom left works yet)
I can't see more than one Beit Dejan in your save game. Are you sure you're not just misreading the various events that build other castles? I can see that Beth Gibelin and Belvoir are both built, and those spawn from events too.
Now that I re-checked the file, I didn't find more than one either. I could have sworn. Maybe I did mix it up with similarly but not identically-named baronies? Sorry!
