1.0.4 adds the Vehicle file in the folder, hopefully fixing this issue.
However... 1.0.3 is an unplayable version. I apologize sincerely for that. The player's starting position is WRONG, that is because I uploaded a test version by accident.
Version 1.0.4 fixes that, but you will have to start the game from scratch in the new version as the save file from 1.0.3 will be unusable.
Thank you for visiting this page, I hope you'll be able to play the game as intended now! Please let me know if you find any more issues!
