CTD on the CS turn

[ITC]

So, constant CTD during Crusaders States turn.
Here is a log:

Spoiler Alert, click show to read: 

19:33:42.765 [game.script] [error] Trigger processing error in <priest_pagan_disciple>
: PopulationOwnReligion needs a character in a land region.

when testing <PopulationOwnReligion> condition
19:35:03.914 [system.rpt] [error] Medieval 2: Total War encountered an unspecified error and will now exit.

It seems Meneth (I don't have MSSC installed) is right, here is his post

Looks like it's caused by a faction going extinct. Try preventing whatever faction that is from going extinct (moving the killer army usually works great)
Edit: since it's only turn 20, it's probably the Crusader States getting crushed. Should help you find the culprit.

So how can I solve the problem? CS are too far for my help.

Cheats. Character_reset, move_character, etc.

Thanks!
Didn't help.. moved two strong armies to the CS, and 2 priests. Unfortunately the same CTD.

use "surrender_regions jerusalem" to kill them off.

Thanks for the help bane!
It seems I've misinformed you. It was not CS, but something similar to this problem (But I have nerely no submods installed except Devy's Real Rebellion and permanent forts. Already tried to switch off Real Rebellion).
May be rebels, and may be something with traits.
I made a search and found no solution to this.
