Hey everyone, just gonna write it here to be documented.
Not sure if this is the way to report a bug or not, but maybe it could help a friend.

The weirdest thing just happened at the mine road. While I was battling the other bikers for weapons, an unconventional bug happened.

After I lost one of the battles, I could not find any bikers anymore, after a while, I noticed I could not even leave the mine road (no buttons nor exit signs). When I pressed F1 to show the classic game, it was like I was walking backward. The road sprite was moving forward.

So, I had to restart the game.
That was weird.
