Got it. It's vehicle specific usage of command motoroverloadrelaythresholdtoggle that lacks call to method setting gauge animation.
void TTrain::OnCommand_motoroverloadrelaythresholdtoggle( TTrain *Train, command_data const &Command ) {
if( Command.action == GLFW_PRESS ) {
// only reacting to press, so the switch doesn't flip back and forth if key is held down
if( ( true == Train->mvControlled->ShuntModeAllow ?
( false == Train->mvControlled->ShuntMode ) :
( Train->mvControlled->Imax < Train->mvControlled->ImaxHi ) ) ) {
// turn on
OnCommand_motoroverloadrelaythresholdsethigh( Train, Command );
++Train->ggMaxCurrentCtrl.UpdateValue( 1.0, Train->dsbSwitch );
}
else {
//turn off
OnCommand_motoroverloadrelaythresholdsetlow( Train, Command );
--Train->ggMaxCurrentCtrl.UpdateValue( 0.0, Train->dsbSwitch );
}
}
}
should do if I'm reading it correctly. Will be fixed in future release.
