I just started playing this game. I have not closed the window/game since I started playing 9 days and 9 hours ago. I can't remember if Valentine's Day season was going as soon as I started playing, but it seems to be endless at this point! I guess I will close the game and reopen and see what happens, but I kinda liked having it going this long. I've baked 73 trillion cookies, which is not much really. And it won't take 9 days to get back to that amount.
I searched but I didn't see anything else like this for Valentine's. I didn't dig too far to see if this has happened with people beginning the game during other seasons.
