[quote name='ZerotypeX']Also, tried to get the IWHBYD skull, did the ring thing, picked up the skull, saved and quit. Went to check what skulls I got and it didn't show up. Did thise happen to anyone else?[/quote]
This is exactly what happened to me. So I picked 'resume single player game' or whatever that first option is, and went back in. I had to jump thru all the hoops again, I got the skull again, and then left the level and started the next level. Then I saved and quit and I had the skull.
I think you have to pass a checkpoint to actually get credit for a non acheivement skull, but there is no next checkpoint for that skull, its at the end of the level, so you need to start the next one.
