When you were getting the item boxes, did they take a long time to cycle through and actually give you an item? I have noticed that sometimes when I play online, if the connection gets weird, the item boxes will do this, and I will start repeatedly getting either coins, or sometimes (if I'm lucky) it will give me nothing but mushrooms no matter what place I'm in. When I'm in first I usually get a mixture of coins, bananas, and green shells. I've also noticed that it typically happens to other people at the same time. There have been moments where I noticed that others around me where just using mushrooms over and over again. I think this may be a default if it has trouble connecting.
