Hello, this bug happens with Every Player, depending on the Scenerio.
This bug is known to cause Vehicles to what i call "Dead-Stop", but i will get to that in a second.
Here is an Example of how the bug occurs:
Driver 1 & Driver 2 are driving on the Same Road, Same Direction, going 40+ MPH. Driver 1 is in the Front, and Driver 2 is in the Back. If Driver 2's Vehicle even so touches Driver 1's Vehicle/Trailer, Driver 2 "Dead-Stops", meaning Driver 2's Vehicle AND (if applied) Trailer Stop in the blink of an eye where Driver 2 goes from 40+ MPH to 0 MPH. And often causing tons of damage to Driver 2's Vehicle (Sometimes Trailer).
HOW TO RE-CREATE IN-GAME?
When you drive behind someone & you crash/touch the back of the driver in front of you, this bug will occur nearly 100% of the time.
NOTE: Driver 1 will usually take NO damage, if any 1% - 5%. But that is Rare.
This has been a bug ever since TruckersMP has Launched. And this bug ONLY occurs on TruckersMP's Multiplayer, if you start Euro Truck Simulator 2, and crash/touch the back of an A.I. driver, then this bug will not occur.
