Easton Axis HIT Insert "issue"

[Vizsla2]

I've been shooting Axis arrows since ~2008.
I'm at work, so no picture, but I shot a buck and thought I broke my arrow.
But on closer inspection, my shaft is fine, but the broadhead (Ulmer Edge) entered in front of the front shoulder and burried into the bone in the opposite leg. Somehow, the broadhead stuck and pulled out the HIT insert.

Over the years I've had a few bad shots and pulled and pulled, but never had a field tip pull out the HIT insert.
I'm curious... Is this fairly common? Thoughts?

Not enough glue on it would be my guess.

I have never had a HIT pull out of an axis or injexion when using the supplied epoxy, and have been using them for many years. I used to use gold tip shafts and I had inserts pull out all the time!

I think age could have something to do with it. This arrow is 11 or 12 yrs old with orange and green logo. I still have about 4 of these arrows left.
