Can't find the ship wreck – Last Day on Earth: Survival Review

When ever I'm playing the supply drops, dealer , pitstop plane crashes and ship wrecks show up at the beginning of the game when I restarted during a new update where are you guys brought the Christmas update . After a day or two of playing the game I noticed that the plane and the shipwreck weren't showing up like they regular do. I can play for hours and not be able to find a crash plane or a shipwreck I don't know if this is a glitch or anything but I'm hoping you guys can fix it.
