I completed the whole game except for a couple of dark world levels in the last chapter, and have the achievements to show for it.

Now I log back in to find nothing, no bandages, everything locked just like the game started brand new. My times are still on the leaderboard!

For the love of god someone help me   

Hey! Just joined the forums now to ask about this weird glitch in 3-9x.

 After dying a bazillion times I glitched through the locked door and saved bandage girl in 2 seconds... 

Has this happend to anyone, and is there a way to delete my score from the leader boards, I really don't want to get the achievements by cheating.
