Al it may do any of the above, and it may stay together for 10000 shots or more ya just don't know. I know it sucks to be out of the 150$ worth of material but its part of bow building, even the best bowyers in the world make fire wood every once in a while.
Double check your form for low spots, high spots, or maybe a rounded over edge and get back on that horse. If ya do find a abnormal part of your form check out Kenny's form build along and use a router bit for a perfect surface.
Good luck
