PS - No third party plugins and behaviors were in use.
Steps to reproduce:
1. After the screen scrolls 1 x Width, you need to use your character and jump to collect a cluster of 2 coins (bunched close together). Keep trying and the error is bound to occur. I suggest the up arrow key while you are directly under two coins. I attach a screenshot illustrating the problem:
2. The problem appears to go away after I comment out the function calls to the audio.
Uncaught TypeError: Cannot read property 'uid' of undefined (b is undefined)

It should not be crashing.
