Bug on Minion Rush for iPhone 4 16 GB

My life as a software tester, sometimes, when I’m using a certain application, my behavior to that application is like doing a test in it, beside phone application, sometimes home appliances, and so forth. Yesterday, I played Minion Rush, created by Gameloft, on my iPhone 4, and at the same time, my friends sending me several conversations using whatsapp, and here goes the bug.

On Minion Rush, I was playing on El Macho’s Lair, at the sliding deck, at the same time three friends of mind sent messages through Whatsapp. I kept playing and ignore the message, however, although Minion had finished sliding, the character was behaving like it’s still on the sliding, even when it crushed with the green statue, it didn’t die. Here’s the screen shot.
