Hello Forge 

            I currently trying to fix the rider's position in the dragon, the rider should be in the dragon's shoulder, basically my mod is just a modified version of another called Dragon Mounts, the allows us to have the source codes just as long as we tell users that it is his mod but we just edited it a bit and that's what I did. It is imple in 1.7.10 because of the updateRiderPosition Method but now in 1.10.2 it is now gone, the original mod's source code is here : https://github.com/ata4/dragon-mounts. Is there a way to fix the rider's position cause if not I get this weird glitch
