Use simu5g to obtain vehicle speed information, and there is a flash back phenomenon

[hezhongyi]

When I use this function to obtain the vehicle location information, it can operate normally：
veins::VeinsInetMobility* vehiclemobility = dynamic_castveins::VeinsInetMobility*(getParentModule()->getSubmodule("mobility", 0));
When I add this function to obtain the vehicle speed information, the simulation flashback occurs：
veins::TraCICommandInterface::Vehicle* vehicleCommand = vehiclemobility->getVehicleCommandInterface();

simu5g1.2.1：This problem will occur When I use this function to obtain the vehicle location information, it can operate normally：
veins::VeinsInetMobility* vehiclemobility = dynamic_castveins::VeinsInetMobility*(getParentModule()->getSubmodule("mobility", 0));
When I add this function to obtain the vehicle speed information, the simulation flashback occurs：
veins::TraCICommandInterface::Vehicle* vehicleCommand = vehiclemobility->getVehicleCommandInterface();

Simu5g1.1.0 can obtain vehicle information, speed and location, but when there are many vehicles, such as more than 20, the following situations will occur：
