First of all i have to say that this addon is the best IC² addon ever!!
But while playing MC yesterday I encountered a bug:
I tried to build a hunt-for-red-october-style russian submarine equipped with nuclear rockets. I built a mechanism which triggers a piston which keeps the rocket compartment safe from the water and moments later the rocket so that the redstone circuit triggering the missile isnt destroyed by the water.
The problem is that the the rocket obviously sees the water as solid blocks which caused the missile to detonate upon touching the first water block resulting in a gigantic explosion destroying most of the surroundings.
I would be very grateful if you could fix this in the next release.
