cant pick up skulls on mcc (halo3)

Hi everyone, I have an issue whereby i can see the skulls but cant pick them up, regardless of which difficulty i set it on. I can only pick up the iron skull and black eye skull and thats it. Ive tried looking around, seeing if anyone else has this issue but so far to no avail. Ive tried restarting the game and reseting my xbox but so far nothings worked. Any ideas how to fix this? thanks

I haven’t heard of this one, but you should probably post it over in the Support Thread so it can more likely get noticed by the right people.
