ok redstone wire works with blocks but still not around corners so it would take a lot of redstone wire going around corners, torches work on torches but repeaters and comparators are dead against blocks, comparators are not lighting up redstone wire
well i am working on 16w42a and it still does not work and it has messed up a lot of machines like simple mono stable circuits, t-flops, pulse extenders, and/or/nor gates pretty much any machine that required a left or right turn that can't (or shouldn't) have a direct redstone circuits (sorry the observer only goes straight like a T-Rex) it needs to be fixed or another way of making the corners work corectly needs to be given
Thank you
Guess I'll just add my two cents worth
It works with redstone torches.
