Heya anbeck and thank you for the report!
I am having troubles reproducing it myself, but have nonetheless sent it over to our development team for investigation.

If you manage to find any more detailed reproductions steps that make it happen guaranteed, then please update your post with a reply!

anbeck said: It just happened again in the way the others describe it: I was at my liege's court to petition him. My petition was denied, so I chose the "Wait, hear me out..." option which immediately teleported me back to my own court where I kneeled before my empty throne, unable to unpause.

So as reported by others, the "insist" option is probably linked to this bug. I do not remember having been presented with or choosing such an option when this bug occured the first time, but I may have clicked too fast to notice it.

Maybe a long shot, but do you happen to have a save left of when it happened?
