We need a hero, who can bypass the traps, that wolf put into this game.
The ominous bridge bug is no bug. Instead it's a player trap to destroy their save files, when they're using a crack for this game.
So when you use the provided crack for 5.60 or earlier, you'll get trapped by the game into this problem.
The only thing you can do then, is to delete this file or better to delete the entire game and your userdata from ***/user/appdata/local/User Data, otherwise you'll encounter more troubles while trying to use old save files, again. Also you will get errors when using the same save file, after steppin into such a trap.
People with official accounts to this game won't have such troubles and crossing the bridge works fine.
But when they also implement the crack to get those costumes, they'll also get trapped.
So, it's true, when wolf wrote, those files get verified via some server or something like this.
I just wanted to state that here, so people who're working on the next game mods/ cracks can consider this and try to bypass this somehow.
