Jina kala can be set in both parameters , HTSetting & TantraParam , if you have HTSetting open Tasklist tab , and find ID: 2929 " Jina Kala " @ ID: 153 you can check it there the ID corresponding to the TantraParam , all you need to do is Delete or make null to permanently stop the Jina Kala Event in specific map. see the image below

If you want to open Karya Dungeon first thing you need to do is find the portal declaration in NPCGener, make sure that Karya Dungeon DwPortal ID is okay , then proceed in your HTSetting tasklist tab find the Event Portal for Karya Dungeon i believe there are two coordinates in both Map for Mandara Village , i dunno what coordinate is that Lol
