I believe I am not the only one who has had this issue before. Once you get all the flying presents that are possible to get in single player playthroughs, they stop spawning entirely. Because of that, the last two remaining flying presents (that can only be found in multiplayer games) do not appear. I have been trying to find them for weeks in multiplayer games and I have yet to see a single flying present.
I have noticed that devs mentioned this would be fixed in a future patch, but that was a month ago. Is this fix going to happen eventually or should I just consider this will never be possible to do?
