I can't seem to find the error in my code.. yes I know it isn't documented yet but it's fairly straightforward and simple. I honestly can't figure out why it crashes when run, it doesn't crash in the same sequence or at the same call everytime and without a debugger I am having real issues figuring out my problem.
Thanks in advance for any helpful clues.
