Wind Zones and External Forces causing crash after exiting game.

Hello, Whenever I include a *Wind Zone* or a Particle System with *"External Forces"* in a scene, the game will run just fine, however after quitting (Via the X button, or Application.Quit()) I get a crash error message. I've already posted this on the forums, but thought I should try my luck here as well. The specifics are in [this post.][1] [1]: http://forum.unity3d.com/threads/187266-Wind-Zones-and-External-Forces-causing-crash-after-exiting-game-Unity-4-1-5?p=1279466#post1279466
