First, all this bugs happens with the 2 null cell types, so keep that in mind:

1 - Cannot be powered by a lever, redstone torch, pressure plate or button, oh, also redstone wire!:
-Null cells can only be powered by BP wires- :





I don't know if this is intented, because levers, redstone torches, pressure plates, buttons and redstone wires transport redstone signals, and the null cells transport bluestone signal, correct?
If that's correct the first bug is not a bug, just an intented feature, sorry, if not, this is a bug.

2 - They not transport bluestone/infused teslatite signal to other null cells:

.

You already reported it the other day (though it was on my stream or on twitter instead of on the issue reporter).
Them not interacting with redstone signals is more of an unimplemented feature than a bug and not connecting to eachother I still have to find out, but it should have an easy fix :P

Fixed!
