Hi,
ever since 1.2.9.1 is released two of us in our realm have been randomly teleported to / into a (none existing) minecart nearby on a road.

If you stand still you get teleported into the minecart, if you're walking while this is happening you're out of luck because you will end up in lava.

I'm still not sure what excatly causes this problem, but it's pretty annoying. It might be an Enderman porting nearby or something. We play in survivel and don't have cheats activated.
