I found a wreckage which used to be 6 police cars. Out of curiosity, I decided to fix it up so I would have a car with 6 v8 engines.
At first things went smoothly, I fixed a seat, a control and one of the engine block, then I installed several wheels and filled some gasoline. The engine started without a problem and I drove it to another location for further fix.
Several days later, I noticed I couldn’t move the car anymore, despite the menu showed no obvious problems, the v8 engine was good and there were enough wheels. The car was in the middle of a road and there was no obstacle. It just said the car was too heavy, while the menu showed it had a safe/max speed of several hundreds km/hour.
Oddly enough, even after I fixed all 6 engines using debug menu, the car still could move. Removeing all wheels and installing them to more trivial positions did nothing.
Any ideas?
