Is this one of those situations that I’ve learned a little bit about regarding how add-on developers can build add-ons in such a way that certain files override those of the sim that are not meant to be overridden? (I SERIOUSLY cannot believe this is even a “thing” with the SDK, how did someone not put the kybosh on this when it was first discovered as a possibility??)
I noted this as something that I was doing when I was developing my mod for the 307. The way I had arranged the file structure of my fixes to the 307’s Sperry Autopilot was affecting the DC-3! I had to change the file name of my fix to something unique and I also put it in a directory that was unique in order to keep my fixes “local” to the 307.
I know ORBX is a major dev, but they probably sell scenery that is developed by several different sub-contractors (I know this is the case with Just Flight’s KSBP. When I’ve had issues with it their support staff told me they had someone else develop it) and its possible these contractors aren’t as careful with these files and are affecting sim-wide files that shouldn’t be affected.
I know, too, that Raul as FSReborn has been extremely frustrated by this. He has reported as such on the MSFS developer forum. Much of his time is spent on support for his aircraft. Far too often he discovers that some other add-on is affecting files that are then affecting his aircraft. None of which is his fault.
Anyhow, I’m wondering if this is what you’re seeing here with scenery.
