To bad, sorry to see that Nathen; it was a really nice bow!
I believe you did not give it enough longitudinal support!
I had a splinter lifting on a bamboo backed Osage I have made years back after I shot it for a very long time; after supergluing the splinter down I epoxied on a 4" long patch of umbrella silk, saturated that with epoxy from the outside, wrapped into the wet glue and saturated that wrapping again from the outside, using Aceton to get a nice smooth surface.
Shot this bow A LOT in the past two years, pulling it to 29"!
