Object removing it self.

So guys, i’m trying to make the Crate fall on the ground, when the crate is tapped, but for some reason, after the screen is loaded i have 1 second or less to click on the crate, and the crate will fall, if i wait to long, i click, i get to log messages but the crate does not move.
