Today when i was playing TSC i was trying to get to that ledge with the skull.on my 49th try (counting!) i got there i stood a foot away from the skull and died.On the ledge right in front of the skull Masterchief literally fell through the floor!Is this normal?
(I got the skull later and it happened after i got it.)

When you die, MC’s body can sometimes fall through stuff, no problem there.
