So the issue seems to be with loading a specific route FPST - SBFN it would be nice if someone could try loading this in on their own sim. If i try it via the load option or just simply using the built in MSFS2020 router finder low or high altitude airway it will crash. Not sure why it took me so long to work this out, if i load any other route it works fine, even if its XXXX - FPST or SBFN - XXXX it is fine. As soon as i try to load the configuration route of FPST - SBFN by any means, it crashes the sim.
