I appreciate the comments. I am going to use safety wire and duct tape on all the pin dings. And, I'm not positive about the ring ding, I didn't install it and didn't check it; it was the upper one that connected at the jib, not the lower one that can be adjusted. What made me think the pin snapped was the loud snap just before the mast fell, which sounded like the pin popping.
As far as aligning the arrows not mattering, I'm not so sure. Let's say the mast is pointed at 0 degrees. There is freedom of movement, but it is limited by the bolt holding the ball hits the inside of the mast. But, at 90 degrees, it has free movement.
The good news is that I've had someone look at possible mast damage, and I was lucky enough to have it be very minor and superficial. But, I'm going to tighten the side stays to restrict the mast movement to ~+/- 45 degrees, wire as well as tape and safety wire the ring dings. I appreciate the suggestion of taping, I just thought damp tape tends to come undone, but duct tape does tend to hold for a while, and I can always replace it. Thanks for the suggestions.
