Lovely! Thanks! =)

I tried ticket authors repro mission and can still reproduce the behavior almost every time. Front wheel turned sharply right, vehicle slowly drifting/rotating left. Can also add it make no different if SR_Hunter is a "B_MRAP_01_F" instead of a "B_Soldier_F" and placed on the same spot as the empty vehicle.

I have attach a folder called "hunter_wont_drive.Altis".
For me the vehicle always stops at the slope (100%).
Please let me know if your vehicle doesn't stop!

Can also add that alt-tab out and in from the game in debug camera mode make the camera move very fast! You have to remember to press alt again when alt-tab back to the game... I often miss that and end up some kilometers away. doh

Confirmed! Also have the same problem. See attached mission pbo.

Does the command playGesture ever work? Maybe do some spring cleaning and remove old junk that is not used and aren't working!

AI crew still leave the vehicle when flipped. Tested with:
vehiclename allowCrewInImmobile true;
vehiclename setVectorUp [0,0,-1];

I also have the same issue, but this is when creating waypoints in editor. I notice it’s not on the exact location as I write. Ex. Group X addWaypoint [[21987,4821.83,0], 0] the created waypoint will be at [21945.5,4862.34,0].

It doesn't matter how much I try micro it m by m it never gets exact... then why the zero in the end (placement radius) when it don’t uses it. This is also a problem for me when I want a helicopter (Huron) to hover over a vehicle, I get the same result when using (getpos) as if I use the coordinates [x,y,z].

Can understand if it’s adjusted for AI’s on the ground and the location is not accessible, but for the air vehicle there is nothing to hinder them...
My workaround for this is setpos getpos but it ain't pretty =)

EDIT: Found [group player, 1] waypointAttachVehicle object; lol feeling a little bit stupid now. But still I think it would be great if the waypoint come on the exact location it were created. Ooh and I can't make the waypointAttachVehicle attach to "Land_Device_disassembled_F".
