This is another variant of the error:

[jomini_script_system.cpp:262]: Script system error!
Error: Undefined event target 'recipient'
Script location: file: common/important_actions/ket_important_actions.txt line: 419

Thats super weird... its like you're using a OLD file...
Try unsubscribe from the mod, load the game without it, and reinstall the mod again.

Hi Ketaros, I wen through the whole process; unsubcribed, exited Steam, loaded and started a game, exited the game, subscribed. In the launcher, I reloaded all mods and cleared out the cache. Then I started a new game, and the errors started again and crashed my game. If I disable Omniscient and play with the same saved game, I can play without crashing... it's possible that its a conflict.

Thank you

That's my mod list.. the load order is not exact

War Alerts can be the issue. Try without it. just to eliminate this, than I will see how to make compatible.

That's great that you know what it is! -I would rather have your mod than War Alerts, and if you can make them compatible that's all the better. Thank you

On the save game that I have been playing, I disabled war alerts and enabled Omniscient, and all was well for awhile and then the game crashed with 200k of the same errors above. I played it for hours with War Alerts enabled and Omniscient disabled.

Could be another conflict or that Omniscient errors are occurring because it's a save...although this game started with Omniscient enabled.

Its late now, but tomorrow I could try a new game with all of the same mod enabled, except War Alerts if you think that test would be of value

Yes, try a new save only with the Omniscient and no War alert.

ok, I started a new game with only Omni in the playset. I downgraded to 1.7.2 first.
I still received a massive number of the same error messages and the game crashed quickly.
I verified in the debug.log file that only Omni was used. I verified the game files.

Is it just me receiving these errors?

Yes, its just you :(

This is weird! -I am not a slouch when it comes to technology, (really not trying to sound arrogant!) I have been in IT for ~25 years designing, implementing and supporting networks, wireless, security, and servers(Linux and Win). Built PCs, am Cisco and Microsoft certified, have done a little work on mods so it goes to show you that anybody can be flummoxed and run into issues!

I am going to delete your mod manually from the workshop directory and test that, and then perform a fresh install of CK3 if that doesn't help

Well, I figured it out. Manually deleting the entire Omniscient directory resolved the error messages tat I was receiving. Usually going "nuclear" is not needed however all of the usual things.

And the crashes that I was experiencing were due to my overclocking my video card. I tested the overclocking with a variety of tools and adjusted it to stable settings. And then I played other games on it, so I didn't link the CK3 crashes to overclocking. I had taken ~8 months off from playing CK3 after playing for ~1,500 hours, and it just didn't occur to me that changes made to the PC months ago were something that could be it.

Oh well, thank you for the help. And I have now switched to your Interface is King mod, and it is spectacular.... everything looks so much better!
