I encountered something, my miner in 1.2.0.2 seems to not give my mining pipes back; i even put chests on all of its sides and not one pipe ever came back, vanishes forever. Whereas in 1.1.3.7.4.3, i used my miner again and it gives my mining pipes back through the chest.
is this a bug or a new feature that pipes can only be used once in 1.2.0.2?
