Hi all,
If you are using/working on/releasing mods, be aware that today’s patch updated the manifest.json for all airplanes. Any mod needs to have its manifest updated to match the latest version, otherwise the mod will not appear in game. (Who spent the last 30 minutes wondering what the heck was going on?? THIS guy!)
Please have some patience and give mod developers some time to catch up and update their work!
