One of the side benefits of the technical problems over Christmas was that the drops, chests etc were proved to be random. You would know that as you may have to open the same chest or land the same plane ten times and each time it could be different. Online or offline, night or day, en-mass or one at a time seemed to make no difference. One time you would get two quest items, the next nothing, over and over. I like to land planes en-mass as it does feel more rewarding, but I don't for a minute think it has any impact on the overall randomness of it.
