Morning! I've been enjoying the L1011. Haven't really experienced any issues until today. During cruise about 600NM from TOD I realize that my aircraft is beginning to slow down. I look and the throttles are fully retarded. I have the autothrottle in TM mode and have for the entire flight. It's commanding M.082 cruise... however we're now nose high and slowly descending. I can't get the throttles to do anything. So I disconnect the AT but the throttles do not respond to my joystick imputs. Testing in the settings it's working correctly, but no movement from the throttles. So I program keyboard commands for throttle increase/decrease and I can see the throttles respond a milimeter or two but not fully increase. They just instantly return to idle as if there's a lock. I can't find anyway to get the aircraft to increase thrust at all - so I had to exit my flight. Any suggestions on how to prevent this or correct it if it's happening? Using the default united paint and version 1.0.8.
