I had 4 buns prior to this event which all seem to work perfectly.
Now the rewards for the event are buns and i only have 3. I assume my other 4 were deleted from the game. Why is that?
Buns have a use by date. If this passes you cannot use them. Often they will not disappear from your inventory unless you try to use them. If they release new buns, to avoid issues I think they force any unused buns to disappear
