blackhornet - I was mistaken; you were right. At some point I had a second array in my object list and was thinking that Line 2's array reference was to that now-deleted array. I toggled the event as you suggested and that cleared the problem up.
However, Ashley, you may still have reason to check and see if that is a bug. Technically, I don't see why any error should have come up from how I had things...but that's just a testimony to my ignorance on software programming.
