In theory nothing has been changed in submodels in a long time, and <aero-stabilised> remains a bool. However I have been making changes in AIBallistic, so the problem probably lies there, and I'm investigating. I can sort of reproduce your bug, but here all the submodels behave in the same way. If they don't then it is possible that you haven't enabled AI Models.
