Vehicle get stuck after depart from garage

I met a problem that vehicles always get stuck after it depart from garage.It happened on both two maps.All the vehicle have this problem.No message about unit can't use that area.

Mod version is 0.9.2 with steam edition of EMERGENCY 20 (4.2.0).I reinstall the game and mod but it didn't work.

Sometime the cursor icon will dispaly it can move,sometime it can't.I can order crew member get out the vehicle.But whatever it display,the vchicle still can't move.

This problem only happened in my computer.Other's game can move the vehicle correctly.

Thanks your reading.
