Hello there, I have a serious issue with my spigotMC at the moment. It started when I updated to 1.10.

For some reason, I can't craft. whenever me or a player opens their crafting menu/ crafting table, they can place items in the crafting tab,e however when I try to craft to a recipe (for example, a button), the button flicks in the output slot for about half a second before disappearing, and nothing is in the output slot.
I have just updated my spigotMC to the latest version, however, it has gone from being 4 versions behind to 2 versions behind.

Please, can you help me quickly, because it's kind of hard to have a PvP server with no crafting!
