No, but (pun not intended) maybe the material "pulled the proofhide out of the leather (speculation only). Some apply heat for a period of time to let the proofhide soak in further as a time accelerator. I would just wipe it off and keep riding.
This may also be the reason why so many say not to apply to the top side!
