Here is my repro - https://drive.google.com/open?id=16bys21uti-pXbCH1w4eHGkL0BHPMtmGR
here is the repro-actions:
1) GET IN YOUR TANK ( as commander )
2) GET JOINING WITH NEW SQUAD, AND GET NEW MOVEMENT COORDINATES ( from your commander )
3) You already have Activated Waypoint! afer this SELECT IN COMMAND MENU -command "Next Waypoint Command" (1/8)
4) YOUR DRIVER WILL NOT EXECUTE THIS ORDER!
5) NOTE! BEFORE 1.80 THIS WORKS GOOD!
So you can see that in bundle with several waypoints this stops working
