Yep. The very first longbow I ever built. I glued the cut out section back in the riser and put overlays on the back and belly of the bow. Hid my mistake pretty well, shot it for years after. No longer have it, and can't remember what became of it.
I have done about every stupid thing you can think of. I once glued a tapered lam in backwards in one limb of a one piece recurve. Talk about a funny looking profile. LOL Drilled holes for quiver bushing on the wrong side of the riser. Probably a few others that I thankfully no longer recall.
