Scary Situation

I had big plans to ride tomorrow at a local track and I just finished changing the oil in my LTR, and when I was putting the oil filter cap back on, one of the bolts just broke off. It didnt even get tight or anything before it broke, it was just turning loosely then just popped and fell in the floor. Ive never been so pissed in my life. Luckily, I was able to get it out and got to Advance Auto Parts at 8:55... They close at 9. They had the bolt, only in a better stainless version so I can ride again. Just figured I would let you all know the stockers seem a little weak, and wondering if anyone else has had the same problem??
