So i was building a theme park on minecraftfor the xbox one (not the newer release) and i built 5 rollercoasters, so then i downloaded the newer version for minecraft and then i retrieved the theme park world from the older version of minecraft and i started building new rides. I wanted to play about with some of the rides and then i realsied that the minecarts were going seriously slow. I also discovered that the carts kept getting stuck when nothing was touching the mine cart. This is a big problem for me because it has affected everything and it is a big deal. Anyone else got the same problem?
