File:Fur Fighters Viggo's Revenge (PS2) - I can't even explain this glitch...

Description
Doing the game as normal, beaten Beaver Power 100% and saved Rico's wife Juanita, noticed Tweek's mother isn't at the house yet she's suppose to be there when you clear New Quack City. I go to New Quack City and the cutscene for visiting the area for the first time plays again... and EVERYTHING THAT I COLLECTED HAS BEEN RESET. TOKENS AND EVERYTHING.

I personally have NO IDEA how this even happened. No cheats were used at all and I honestly don't know if there's even a level select for this game. I wonder if this has to do with using a beaten up copy of the game as it has many scratches yet it's playable but if not then this is perhaps one of the most random glitches that I ever countered in my life. At least you get a extra 300 Tokens and 29 Babies but still... HOW DID THIS EVEN HAPPEN?
