Since the A32NX was made into its own aircraft category, I have downloaded a bunch of specific NX liveries from the .to site (rather than using FlyByWire’s converter which led to problems with the game). Curiously, however, when I boot up MSFS, there are only a limited number of A32NX liveries available in the game, despite the fact I have loaded perhaps twice as many options in my Community Folder. Does anyone else have this problem and if so, is there a solution?
There could be a conflict somewhere with your old liveries as well. Try to move your old liveries out of the community folder and just have your specific A32NX liveries installed. See if that makes a difference.
I don’t have the problem myself because I restructured the liveries I downloaded from flightsim.to into my own livery pack while also changing a lot of stuff to standardise them together.
