I tested and yeah triple green shells, triple red shells and lucky-7 are crashing. They are crashing because the amount of these items is too high for the game's limit when all players get a triple item!
I removed them, download the 2.0.0 update...
I added the Control Bullet Bill to the last update. To know how it works click on the (i) that appears on the bottom screen when you highlight the code.
One time was there and they had forgotten to get it out of the freezer. Manager came over, said that and gave it to us for free still frozen to take home and eat later
