Started today (16.05.2018) GSX liveupdate, I think there was an update: was anyway surprised to notice that I saw no GSX services and Couatl in the Add-Ons menu after an aircraft change.....
I started with my default A321 on my home airport, everything ok, GSX is on the Add-Ons menu as usual, I even saw the report "Airport Cache Loaded Succesfull" on the greenbar. Then, I changed the aircraft ( no matter wich one, I tested different aricrafts), after loading the new aircraft GSX disappeared, in the Add-Ons Menu is only the Addon Manager: I checked with the Addonmanager if GSX was activated, positive, GSX marked as registered and active.
Please let me know if this is a Bug, or it is only me with this issue, thanks, Pit.
