• V1.0.11.2173-S10
  • I went to war with L who had vassalized V. I captured a town ("Byblos") from V during the war. V then declared their freedom from L which set us automatically at peace but my war with L raged on. 

    Byblos was then locked in the captured state permanently. I could not build anything, ransack it or, even enter the territory but V also couldn't get it back. I resolved this by declaring a surprise war on V and then just claiming it in their surrender terms. 

    Note that when my war with L ended (prior to the surprise war with V), I could not claim this territory from their surrender conditions either as they were no longer the liege. 

  • This has happened in all 3 of the wars I have had against a nation with a vassal and is easily reproduced (providing the vassal declares freedom during the war!)
  • I no longer have the save, sorry.
