Playing spacechem now for a few days.
I was looking up some of the solutions on solution-net and attempted the fastest dissassembly for methane in nothing works level. From least cycles leaderboard, fastest solution reactor 2 (http://spacechem.net/solution/nothing-works/34239)
Anyway, on his solution the out symbol seems to out two free hydrogens in the output simultaneously, whereas when I try his solution, my out symbol wants to output atoms one/cycle causing collisions...
was this something that changed between versions? If so, then the stats are a bit flawed if the solutions are not replicable on current versions of spacechem.....
