Xbox one skyfactory by volcano

I been playing skyfactory created by volcano and ever since the new nether update. It has created a bug when when I put gravel in to a new it does not drop a item anymore. I contacted help and they gave me links to the market place to see if I could contact the creator but there was no way to contact them, so they Gave me this link. Befor the update the game was working. The net is  a item you but gravel in and it suppose to drop 1 item but does not work now.
