So, I have something that teleports @e[type=MinecartRideable,r=5] to a different location. If I am riding the minecart when it is teleported, the game renders me as being kicked out of the minecart, but if i press the sneak key or have the minecart ride over an activator rail, it boots me out where the minecart actually is. In addition, I cannot place blocks while in this desynced state. No pics because it would be extremely hard to demonstrate without a video.
