Yeah, I posted a message that it requires an update to make it work with the current dev version. It looks like the issue is a lot more difficult to solve. I used to manually add the copilot as an object to the interior model file. Which usually works, but recently I can’t get it to work using the same method. So I had to download Mugz’s mod and that works for a time until the current dev version. Nothing else we can do but wait, I guess.
