Recently when using relatively large area of aerial images (like 3x3 km, built from SDK0.7.0), FS will crash when loading into flight. New findings are when shut down internet data, sim can load safely. And seems two adjacent custom area (around 250km away) can co-exist. I have another 5x5 km aerial images built from SDK 0.6.1 however seems loading without problem, but still suffer from CTD when flying. So far key finding is with internet data “on” will causing CTD when fly into custom aerial area. Wish Zendesk can fix this issue.
