The Wishing Shrub has been functioning fine for me up until now. I granted a wish recently and when I went make my wish, I didn't cancel it immediately after two hours in hopes that it might be granted. I came back today and it seemed my wish had been cleared but not granted, so I went to wish again and it says I must grant a wish in order to make a wish. But I'd already granted a wish and hadn't had a wish granted after that. Do you really only get to make a wish within a certain period of time after granting someone else's wish, before you must grant yet another wish in order to make another wish?

all ungranted wishes are cleared at midnight. since you submitted a wish and it wasn't granted that day, you'll have to grant another with to make a new one. i'm pretty sure it lets you ask for a wish the following day if you didn't submit any, not if you did but it wasn't granted.
