Hello everyone, I have a problem with my current SS campaign. Allways when I try to kill enemy king (when he is the LAST faction's family member) I got a ctd. I tried to kill him with assassins, or kill him in battle, or capture the city where the king is and allways when I do this I got ctd. But this only happens in my current Spain campaign(~150 turns). In turn ~100 Turks wiped Crusader states and non ctd happened, so I don't know where's problem.
I tried to start new campaign (Aragon, and with character_reset and creating Trebuchet with console command and "auto_win" I destroyed Portugal in the first turn and it worked fine and none ctd happen. I would like to continue with my Leon campaign, so any suggestions to my problem?
I'm using SS6.4., with submods RLC and Kingdoms,Empires,Republics. Also I deleted notifications of death of faction leaders in campaign_script, but that shouldn't be the problem I think.
Here's my system log, unfortunately nothing is there..
Thanks for answers
