Description

For some reason the hold speed function in autopilot does nothing.
I tried to send a clip but uploading it was to big but here is a screenshot where it looks like the PID controller thinks the acceleration is just on point while its 20m/s off

Replication Case

I found it has something to do with the tech tree as soon as I unlocked the next node with MJ the speed hold worked.
