First time posting so here goes.
For some reason, the skulls Catch and Famine do not appear where they are supposed to, on The Storm and The Ark, respectively. I've seen videos so I know where they are and I've checked for other skulls and they are still there.
I've followed the recommendations from this thread, starting from the beginning of the mission and with a Normal or higher difficulty. Still nothing.
When I go to the Campaign Menu and press X, all my skulls that I've unlocked are still there (just in case because I saw that some people got their erased).
What can I do? Thanks for the help.
