Because of today's sneak peak into alpha, I could create a character, allowing me to play minigames here, on the site, to fill his results pool.
When I tryed the carpentry minigame, I moved my curson on the green thingy, and started cuting the plank when, suddenly, my progress was at 95% instantly, making me finish the game REALLY quickly, so quickly that when I try to save the score to my pool, it gives an error "Not_enough_time".
That's it. If you want to reproduce it, try to play carpentry minigame on your account managment -> minigame -> choose character -> carpentry, and play it normally.
