After replacing a tire on the back left of the ADA and looting a building, when i returned and got in the ADA it would not budge as though it was stuck on something in the terrain. I initially thought it was the zombie underneath so I had a buddy bump me to see what would happen. when I was bumped it was though the car was sliding on an ice patch. it wouldn't stop sliding until it bumped into another structure. all attempts to reset the vehicle without using admin tools failed. all wheels were taken off and replaced but to no avail.
