I've had a Bamboo longbow and set recurve limbs break just like that. When you get full draw they just go limp.

When you say bamboo longbow do you mean boo backed, or glass with real boo lams? Just curious....  

There wasn't a slide on bowquiver used high up on the limb by chance??? This can create an unfavorable  'stiff' spot in the limb creating a fulcrum where there should not be.
