I am having a similar problem, but kind of opposite - I am running Steam DCS, tried uninstalling and installing the AH64D module, updated everything, and this just started recently - when I engage the flight mode of George AI in the AH64D, it ascends to an altitude of around 1500 feet. It does this if I switch from pilot to copilot, from a hover started with George IA or from direct controls in the CPG seat, it will ascend to 1500' Barometric.
If I switch from a hover to CPG and engage George AI in Hover mode it will not do this, only when it is in flight mode at speed, even if it is 40 mph or knots. Track file attached
THIS IS ONLY HAPPENING IN THE COLD WAR GERMANY MAP SO FAR AS I CAN SEE, IT WORKS FINE IN OTHER MAPS I HAVE TRIED!!!!
