Quote:The crux was that if a creature makes a choice of direction on step x, then on step x+1 it will "turn" in that direction, irrespective of whether that direction is now blocked; and if indeed blocked, then on step x+2 it will make its new choice of direction with the consideration that it has already "turned". Possibly the same applies to Blazes, but I'm still too lazy to check the TWS or the code.
That would seem to explain Blazes. Thanks for the explanation.
(also, hooray for accidentally exploiting dubious creature movements to score new records B))
