SOLVED: Following advice on this page(https://www.loverslab.com/topic/229678-mod-cbo-unofficial/page/38/), I deleted the "Court scene" files in "CBO Unofficial\gfx\court_scene", It actually might have been in the CBO animations folder, I don't recall, but in any case the royal court view now defaults to a courtroom where I can interact with court events/hold court/choose which artifacts to display as normal. I suspect this totally breaks the make love scenes but to be honest that wasn't really something I used Carnalitas or any of it's extensions for anyway
I have the same issue. No matter who I play as or what year I start in etc, the coutr view always defaults to the bedchamber. As a temporary workaround, you canlaunch the game in debug mode, and there is a button at the top that syas "Open view editor" or something. Then there's a drop-down menu in the top left where you can change the room to any of the normal courtrooms, which then let you interact with court events and what things you have displayed, etc. Unfortunately, it does not remember this, so you ahve to go through the whole process every single time there's a court interaction or you want to change what things you have on display or whatever else. It's immensely frustrating.
If anyone knows of a good fix for this I'd like to hear about it. Given how frequent court events occur (especially with things like RICE installed) it's a huge pain in the ass!
