If we have completed and tank x is formed (ui works) and we start playing tank o it will never form (. = not tank blocks). I've tested this along the x and z axis, This does not impact tanks forming along the y axis

Adjoining
(x+1, y+1,z+1) works
(x,y+1,z+1) works
( x+1,y+1,z) works
(x+1,y,z+1) doesn't

While probably not strictly necessary, it does make some things in the pattern matching simpler. As such this was mostly intentional.

It does make it impossible to have tanks adjacent w/o pipes to another multi-block on that adjacent side which is how I ran into this in the first place. It would kind of make sense if there where air blocks in between, but I was thoroughly confused when I tired to make it work
