it massively limits the possibilities to make a machine that will work at all.
There are bugs - yes.
But the actual bugs do not limit you, they just make it harder - you can still do everything (except reactors on frames ).
Also note, that my deployers and assemblers can place wires and machines ( atleast this far), so that must be caused by something you did wrong at the installation. Do remember to use the updated rp2 ( pr5b1 ) and ic2 ( 1.95b ) and forge ( i am using 22.214.171.124 ).
