No ALT or VS control of autopilot post update

[KeplerVerge]

Hello, ive noticed that my aircraft is not able to engage ALT mode and the VS nob is stuck at 1450FPM, no FD either, anyone found a fix or know if its a bug?

The issue would appear to the GTN750 mod that is installed, it also causes AP issues in the BLKSQ King air. disabling the GTN750 mod fixed it for me.

Hello,

Would you mind grabbing me a video of this happening? Not something I'm able to reproduce. 

Thank you 🙂
