Not H4. That has it's own set of issues in this area obviously.
The behaivior I'm getting myself is also rather unpredictable. This has only been going on for the past week.
Mainly some attempts to use this section of code:
angular_motor.y = PI * JumpMultiplier;
llSetVehicleVectorParam(VEHICLE_ANGULAR_MOTOR_DIRECTION, angular_motor);
The angular_motor is obviouisly a vector.
The JumpMultiplier is a value set to give a specified amount of angle when a vehicle jumps.
It has always had it's issues and would never give a perfect amount of rotation. However it has worked well enough for the past few years. Unless massive lag was at play.
Now for the past week or so this usualy results in the a vehicle flipping farther than is normal. Completly upside down at all times. Lag or not.
This is one of the few issues that works fine in H4 however. At least for now.
I would post this in Jira but my last few posts their have either been taken off for no apparent reason or moved to who knows where.
