Now this may seem a bit silly, but hear me out. I am running a server for me and a few friends, but none of us seemed to be able to enchant Tinkers Construct tools. One of my friends realized that we could not do it with modifiers on the tools, so I told him I would spawn in a tool. I used the /give command to give myself an iron shovel, and upon receiving it I was subsequently force-disconnected by the server. I have repeatedly tried to reconnect to the server, but I get a brief flash of game and then the server disconnects me again. I have checked the obvious, like white-list silliness or accidentally banning my own IP somehow, but nothing. I don't understand what to do from here, as there are no actual error reports. Some help on this would be greatly appreciated.
