You can't "look" at mechanism pipes while holding a tinker's hammer or game will crash. To be able to log back in you need to edit your player data; move the location to somewhere else or change the actively selected slot to some other item etc.

oke , great bug :D i can play for a little while, but it indeed crashes when i use the hammer in the neighborhood of the pipes :S thanks for the info :)
