Bone resetting problem with an online game

[legacy-AQT4U2NV]

I have this vehicle that uses a bone rotation code, that makes the player look like they're sitting on a motorbike. Anyways, about 70% of the time my bots will have their bones reset to normal, (after getting off the bike ) and other times they are all twisted up. What can I do to make sure they are normal 100% of the time?



here is my bone rotation code:

 
// added for driver position resetting
simulated function AttachDriver(Pawn P)
{
    super.AttachDriver(P);


   // Pelvis --------------------------------------------------
    PelvisDrive.Yaw=8192;
    P.SetBoneRotation('Bip01 Pelvis',PelvisDrive);

    // Head ----------------------------------------------------
    NeckDrive.Yaw=-10000;
    P.SetBoneRotation('Bip01 Head',NeckDrive);

    // Spine ---------------------------------------------------
    SpineDrive.Yaw=2048;
    P.SetBoneRotation('Bip01 Spine',SpineDrive);
    //Spine 1
    SpineDrive1.Yaw=2048;
    P.SetBoneRotation('Bip01 Spine1',SpineDrive1);
    //Spine 2
    SpineDrive2.Yaw=2048;
    P.SetBoneRotation('Bip01 Spine2',SpineDrive2);

And so on like that for more bones. And my reset goes like this:

simulated function DetachDriver(Pawn P)
 {
    // After the player leaves the vehicle, resets its additional bone rotations or else he'll be all twisted
    // Simply resets everything
    // Pelvis --------------------------------------------------
    Driver.SetBoneRotation('Bip01 Pelvis');
    // Head ----------------------------------------------------
    Driver.SetBoneRotation('Bip01 Head');

First I'd ascertain whether the reset code is running. Try sticking a Level.Game.Broadcast call that displays the bot's name into the reset code and see if it showed up when you see another bot come off twisted.

It seems even the FragEd Special motorbike has this problem online...
