I was playing the Big Dig modpack on the latest version. I found and tamed two chocobos then bred them. I left the area for a bit to mine, and when I came back there were hundreds of the chocobos all with the same name as the one I bred. I have no idea what happened, but I had to use lava to kill them all and rebuild the stables because there were so many chocobos I started lagging. Anyone got any clues as to why or how this happened.
