sorry. I'll change
oh, nvm

I guess I didn't explain the bug as well on the last post. I'll try better.
Confirmed, but don't you expect trains to go crazy when they are colliding into each other?
Started with 5 in the middle, 1 on the outside and was able to get all 6 on the outside.
So its not a bug? there switching tracks. after a while the booster just lets a few minecarts on to the other track.
yeah.
i didn't count but I think so. sometimes they switch faster than other times. also, if you break an outside rail block they all leave the middle and do the other bug where it propels itself on ground (without the rail).
That's also true.
true meaning its in the game? I don't understand. are you testing it?
I mean that I also get that. Sometimes the outer cart just continues over the broken track.
oh yeah. okay. good. its not just me.

Still happens in 1.5.
I haven't tested it yet. good to know. Thanks!

Is this still a concern in the current Minecraft version 1.8.1 Prerelease 3 / Launcher version 1.5.3 or later? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.
