Sorry, but i am understand it correct that you took a working system (which was in 2.9.3) where i can set my BA Altitude correct and also throw CBU 105, break it, and "maybe" in 4 or 6 weeks with next update i will get it back working with a new fuse system?
My personal finding, thats not how updates should work guys, why not keeping a working system till the new system is ready
